Most hand priming tools give you tactile feel as the primary feedback mechanism for seating depth. The seating pressure increases when the primer contacts the bottom of the pocket, and the experienced reloader reads that signal and stops. The problem is that “feel” varies: tired hands apply different pressure than fresh hands, and 200 primers into a session your reference point has drifted. The first 20 primers might be 0.003 inches below flush. The last 20 might be flush or proud – not from carelessness, but from normal hand fatigue changing the pressure baseline.
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool addresses this mechanically. Its micrometer-style depth adjustment dial and hard stop system work together: you dial in the target seating depth on a test case, then lock it. For the rest of the batch, you squeeze the handle to the hard stop. The primer cannot go deeper than the set depth regardless of how much force you apply. Tired hands, fresh hands, variable technique – none of it matters because the tool provides a physical stop that enforces the depth you set.
This is the tool’s defining feature, and it’s worth understanding clearly before evaluating whether the Frankford Perfect Seat is the right hand primer for your bench.
What’s in the Box
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool ships in a custom-fitted injection-molded storage case containing:
- Perfect Seat Hand Priming Tool body – die-cast zinc, hardened steel linkages
- 12 shellholders covering 600+ common calibers
- Large primer seating stem, spring, and guide assembly
- Small primer seating stem, spring, and guide assembly
- Large and small primer trays (100-round capacity each)
- Depth adjustment dial assembly
- Printed instructions
The 12 included shellholders are the kit’s most significant value item alongside the tool itself. Standard hand priming tools require purchasing shellholders separately – typically $4-8 per shellholder. For a reloader loading 9mm Luger, 45 ACP, 38 Special, 357 Magnum, 40 S&W, 308 Winchester, and 223 Remington, buying those shellholders separately adds $50-70 to the total cost. The Frankford kit includes them all.
The 100-round tray capacity is a practical production feature. Standard primer packages contain 100 or 200 primers per sleeve. A full 100-round tray fills without counting, which reduces loading interruptions for any session where you’re priming 50-100 cases at a time.
Build Quality and Materials
At 2.8 pounds, the Frankford Perfect Seat is noticeably heavier than most hand priming tools. This weight comes from the die-cast zinc body and substantial steel components in the internal drive train. These are deliberate material choices, not cost-saving compromises.
Why zinc body construction matters for a priming tool: Lighter hand primers often use plastic or thin aluminum for the frame. Under the squeeze-lever force required to seat primers – particularly stubborn military crimped pockets where 223 Remington or 308 Winchester military brass has already been swaged but still requires firm primer seating – plastic frames flex. Frame flex between the lever and the seating stem means the primer doesn’t travel in a perfectly straight line into the pocket. The zinc body resists that flex, keeping the primer, the seating stem, and the pocket in coaxial alignment throughout the stroke.
The hardened steel internal linkages are the components under constant tension and friction during each primer seating. Steel linkages wear at a fraction of the rate of softer alloy components, which matters over tens of thousands of primers. The Frankford Perfect Seat is designed to be a long-service tool rather than a consumable.
The 2.8-pound weight as a limitation: The mass that provides rigidity also produces hand fatigue at high cycle counts. At 500+ primers per session – priming a large batch of 45 ACP for a competition or 9mm Luger practice ammunition – the weight becomes noticeable. For sessions under 200 primers, the weight is an advantage (rigidity). At sustained high volume, the Forster Co-Ax Bench Priming Tool or RCBS Automatic Bench Priming Tool are more comfortable because the bench absorbs the work rather than the operator’s hand.
The Micrometer Depth Dial and Hard Stop: The Engineering That Matters
The Frankford Perfect Seat’s depth adjustment system is the feature that separates it from every other hand priming tool in the category except the K-M Primer Deluxe Hand Priming Tool.
How the system works:
The seating depth dial is located at the top of the tool. Each click of the dial moves the seating stem’s hard stop position approximately 0.001 inch. The hard stop is a physical limit to handle travel – when the handle reaches the stop, the seating stem has reached the set depth. No amount of additional squeeze force moves the primer further.
This is fundamentally different from feel-based hand primers. On a tool without a hard stop, the primer seats at whatever depth the operator’s hand provides. Consistent depth requires consistent hand pressure on every case through the session. The Frankford’s hard stop removes that requirement: once calibrated, squeeze to the stop and release. The depth is mechanically enforced.
Calibration procedure:
- Set the dial to a shallow starting position (turned counterclockwise from maximum depth)
- Insert a deprimed, resized case into the shellholder
- Place a primer in the tray and squeeze the handle to the hard stop
- Check the primer depth – use a primer depth gauge or feel by running a finger across the case head
- If the primer is proud or flush, rotate the dial clockwise 2-3 clicks (0.002-0.003 inch deeper)
- Test again with a fresh case and primer
- Continue in 1-2 click increments until the primer seats 0.003-0.005 inches below flush
- Lock the setting and run the rest of the batch without further adjustment
After initial calibration, change the setting only when changing brass lots (primer pocket depth varies between manufacturers), changing primer brands (primer cup height varies slightly), or when cases show signs of requiring different seating force.
“Priming to a crush” explained: The depth target of 0.003-0.005 inches below flush means the primer is slightly compressed against the bottom of the primer pocket. The primer anvil is in full contact with the primer pocket’s floor. This ensures that the firing pin strike produces consistent, full primer initiation rather than needing to first push the primer the remaining distance to pocket contact before initiating. Consistent anvil compression is a component of ES reduction – not the largest component, but a measurable one at long range.

The 100-round tray capacity means a full primer sleeve goes in the tray without counting. The tray cover can be tight when new – press it onto the tray body with firm, even pressure around the perimeter rather than trying to slide it in from one side.
The 50 BMG limitation is absolute. Standard hand priming tools are sized for standard rifle and pistol primer pocket diameters. 50 BMG uses a larger primer that requires dedicated priming equipment.
Where the Perfect Seat Excels
Precision rifle loading where depth consistency is tracked. For 6.5 Creedmoor competition loads with Federal GM210M large rifle match primers, 308 Winchester with CCI BR-2 for long-range work, or 6mm Dasher with CCI BR-4 small rifle benchrest primers – the hard stop’s mechanically enforced depth consistency means the 200th primer in a batch is seated identically to the first. This isn’t achievable with feel-based tools over a long session.
Reloaders with variable hand strength or arthritis. The squeeze-lever distributes force across the full hand rather than concentrating it in the thumb or two fingers. For reloaders with hand conditions that affect grip strength, the full-hand lever is more comfortable than thumb-actuated plunger designs. And the hard stop means reduced grip strength doesn’t produce shallower primer seating – the mechanical stop still enforces the set depth.
Multi-caliber production with the included shellholder set. Switching between 9mm Luger, 45 ACP, 38 Special/357 Magnum, 40 S&W, 44 Magnum, 223 Remington, and 308 Winchester requires only a shellholder swap – the set includes all of these and more. No additional shellholder purchases for the most common calibers.
Military brass after swaging. After removing the primer pocket crimp from 5.56 NATO or 7.62×51 brass with the Dillon Precision Super Swage 600, the swaged pockets still require normal primer seating. The Frankford’s solid zinc body doesn’t flex against the slight additional resistance of freshly swaged military pockets. CCI No. 41 small rifle military primers for AR-15 223 Remington applications seat cleanly through the hard stop mechanism after swaging.
Portable precision priming away from the bench. At 2.8 pounds and packaged in its own storage case, the Frankford Perfect Seat is a complete portable priming station. Field use at a hunting camp, reloading at a remote range, or priming cases at a different location from the main press setup – the storage case means all components stay organized and protected.
Realistic Limitations
Weight causes fatigue at very high session volumes. At 500+ primers per session, 2.8 pounds in the hand for sustained cycling becomes noticeable. For reloaders regularly priming 500+ cases per session, the Forster Co-Ax Bench Priming Tool or RCBS Automatic Bench Priming Tool distribute the work to the bench and eliminate the fatigue variable.
Depth dial must be re-calibrated when changing brass lots. Different manufacturers’ primer pockets have different depths. Lake City 223 Remington military brass and commercial Starline brass of the same headstamp designation may have pocket depths that differ by 0.003-0.004 inches. When changing brass lots, recalibrate with 2-3 test cases before running the batch. This adds a brief setup step that feel-based tools don’t require.
Requires shellholders (though 12 are included). Unlike the RCBS Universal Hand Priming Tool and Lyman E-Zee Prime Universal Hand Priming Tool that use universal jaw systems requiring no shellholders, the Frankford Perfect Seat requires a shellholder for each case head diameter. The 12 included shellholders cover the most common calibers, but less common case head sizes may require a separate purchase.
Lever width can be uncomfortable for smaller hands. The full-grip lever handle is sized for average to large hands. Some users with smaller hands report that the initial reach of the lever feels wide before the hand closes on it. This is primarily a comfort issue rather than a function issue, but it’s worth noting for reloaders with smaller hand size.
Setup and Operation
Shellholder installation: Snap the appropriate shellholder for your caliber into the shellholder seat at the base of the tool. Verify the case seats fully with a slight click before testing with a primer.
Primer size changeover (large to small or vice versa):
- Remove the clear primer tray
- Remove the shellholder
- Unscrew the thumb-wheel at the seating assembly
- Swap the seating stem, spring, and guide for the other size (both included)
- Reinstall the thumb-wheel
- Snap the correct shellholder back in
Swapping primer sizes requires no tools and takes under 3 minutes.
Calibration for new brass or primer lot: Start with the dial at a shallow setting. Insert a deprimed, resized case – it must be deprimed; a live primer in the pocket prevents correct calibration. Place a test primer from your current lot in the tray and squeeze the handle fully to the stop. Check depth: press a straight edge across the case head near the primer pocket. If the primer protrudes above flush, add 2-3 clicks (clockwise) and test again. Continue in 1-click increments until seated 0.003-0.005 inches below flush. Run 3 cases to confirm repeatability, then run production.
Primer tray loading: Open the tray cover, pour a quantity of primers on the tray, replace the cover, and gently rock the tray side to side. The primers orient themselves anvil-up through the tray’s geometry. Avoid violent shaking – a gentle side-to-side motion moves primers without causing orientation errors.
Which primers pair with this tool: Large rifle – Federal GM210M, CCI BR-2, Federal 210, CCI 200, CCI 250 magnum, Winchester WLRM magnum. Large pistol – CCI 300, Winchester WLP. Small rifle – CCI BR-4, Federal GM205M, Federal 205, CCI 400, Remington 7-1/2 small rifle benchrest. Small pistol and small rifle semi-auto: CCI 500, CCI No. 41 for AR-15 223 Remington semi-auto. All standard primer brands and sizes are compatible.
Competitors – Four Direct Comparisons
RCBS Universal Hand Priming Tool
The RCBS Universal Hand Priming Tool is the most common direct comparison. The RCBS uses a universal jaw system – no shellholders required for any caliber – and a 100-round primer tray. What it doesn’t have is a depth adjustment dial or hard stop: depth is entirely feel-based. The RCBS is lighter and smaller than the Frankford Perfect Seat. For a reloader who values the no-shellholder convenience above mechanical depth control, the RCBS is the choice. For a reloader who specifically wants the hard stop’s mechanically enforced depth consistency, the Frankford is the choice. The RCBS Hand Priming Tool is the RCBS standard (non-universal) alternative at a lower price, requiring RCBS shellholders per caliber.
Choose the Frankford Perfect Seat if: mechanically enforced depth consistency, the included 12-shellholder set, and a heavier/more rigid construction are the priorities. Choose the RCBS Universal if: no-shellholder convenience across all calibers, lighter weight for extended sessions, and adequate feel-based depth control are the priorities.
K-M Primer Deluxe Hand Priming Tool
The K-M Primer Deluxe Hand Priming Tool is the boutique benchrest tool that the precision community has long cited as the reference standard for tactile feedback. The K-M uses a threaded stem that provides very fine depth adjustment, and the direct feedback through its mechanism is exceptional. The critical difference from the Frankford: the K-M is a single-feed tool. There’s no primer tray – you place each primer individually onto the seating post. This makes the K-M slower than any tray-fed tool. For benchrest loaders seating 20-50 primers per session and treating each primer seating as a precision operation, the K-M’s single-feed discipline and exceptional feel are worth the speed tradeoff. For reloaders priming 100-200 cases regularly, the Frankford’s 100-round tray speed at comparable mechanical depth precision is the more practical tool.
Choose the Frankford Perfect Seat if: 100-round tray speed alongside mechanical depth control is the priority, and single-feed’s tactile purity isn’t worth the production speed tradeoff. Choose the K-M Primer Deluxe if: you seat under 50 primers per session and want the maximum possible tactile feedback with fine threaded-stem depth adjustment.
Lyman E-Zee Prime Universal Hand Priming Tool
The Lyman E-Zee Prime Universal Hand Priming Tool uses a universal jaw system (no shellholders), a primer tray, and a straightforward design at a budget price. The Hornady Hand Priming Tool is the Hornady-ecosystem alternative in the same feel-based hand primer category at a similar price. It lacks the depth adjustment dial and hard stop of the Frankford Perfect Seat. The Lyman is a competent tool for general reloading where feel-based depth control is adequate – 9mm Luger practice loads, 45 ACP competition production, standard hunting rifle loading. For precision loading where ES is tracked and primer depth is a controlled variable, the Frankford’s mechanical hard stop provides consistency the Lyman can’t match.
Choose the Frankford Perfect Seat if: precision depth control matters to your application and the 12-shellholder kit covers your calibers. Choose the Lyman E-Zee Prime if: budget is the priority, universal jaw convenience is valued, and feel-based depth control is adequate for your loading goals.
Forster Co-Ax Bench Priming Tool
The Forster Co-Ax Bench Priming Tool is the bench-mounted alternative in the same precision tier. The Forster’s universal jaw system eliminates shellholders entirely, its sideways-stacking primer tubes reduce chain-fire risk, and its bench-mounted design eliminates hand fatigue completely. For sustained high-volume sessions where the Frankford’s 2.8-pound weight becomes fatiguing, the Forster is the correct alternative. The Frankford’s advantage over the Forster is portability – the Frankford is a complete self-contained tool in a case that goes anywhere. For field use, hunting camp, or loading at a secondary location, the Frankford’s portability is an argument the bench-mounted Forster can’t match.
Choose the Frankford Perfect Seat if: portability, the 12-shellholder kit value, and depth dial control at hand-tool convenience are the priorities. Choose the Forster Co-Ax Bench Priming Tool if: sustained high-volume priming (500+ per session) without hand fatigue, universal jaw coverage without shellholders, and the sideways tube safety design are the requirements.

What to Buy with It
The Frankford Perfect Seat pairs naturally with any single-stage press for the loading workflow where cases are sized on the press, primed with the hand tool, and then returned to the press for powder charging and bullet seating. The RCBS Rock Chucker Supreme is the most common single-stage press used alongside dedicated hand priming tools – its on-press priming arm is excellent but many reloaders prefer the hand tool’s depth control for precision rifle loads.
Additional shellholders for uncommon calibers not covered by the included 12. The Frankford Perfect Seat is compatible with Lee-style hand-priming shellholders if you need a size not in the kit. For 30-06 Springfield, 300 Winchester Magnum, 338 Lapua Magnum, and 7mm Remington Magnum – verify which included shellholder number fits each before assuming.
Dillon Precision Super Swage 600 for processing military surplus crimped brass before priming. The Frankford Perfect Seat will not seat primers in un-swaged crimped pockets – the crimp must be removed first.
Frankford Arsenal Platinum Series Hand Depriming Tool as a companion depriming tool for batch decapping before case cleaning. Depriming and cleaning before priming produces the cleanest primer pockets, which improves seating depth consistency through the Frankford’s dial system.
Frankford Arsenal Vibra-Prime – not for the Perfect Seat specifically (the Perfect Seat uses a tray rather than a tube), but for any progressive press primer tubes being loaded concurrently. If you prime cases on the Perfect Seat before running them through a progressive for charging and seating, the Vibra-Prime handles the press primer tubes. The Lee Auto Bench Priming Tool is the budget bench-mounted alternative for reloaders who want to add a bench station specifically for the calibers the Frankford covers with its included shellholders.
Match primers for the calibers being primed. For 6.5 Creedmoor and 308 Winchester competition: Federal GM210M or CCI BR-2. For 6mm Dasher and 6mm BR benchrest: CCI BR-4 or Federal GM205M. For 6.5 PRC and 300 Winchester Magnum: Federal GM210M or CCI 250 magnum. For 338 Lapua Magnum: CCI 250 or Winchester WLRM.
Primer depth gauge. For calibration verification, a proper primer depth gauge confirms the 0.003-0.005 inch below-flush target. The case head flat-surface test gives a reasonable estimate; a gauge gives the actual measurement.
The case prep essentials guide covers systematic brass preparation that maximizes the value of precision priming – uniform primer pocket depth through primer pocket uniforming, consistent case length through trimming, and clean pockets through proper cleaning.
Troubleshooting
Inconsistent seating depth despite using the hard stop. The most common cause is debris under the shellholder. A single brass shaving or grain of powder between the case head and the shellholder seat raises the case slightly, making the primer seat shallower than the dial setting. Remove the shellholder and wipe both the shellholder face and the case head seating surface clean before each session. Also verify the case is fully seated in the shellholder before squeezing the handle – a case that isn’t snapped fully into the shellholder seats at a variable height.
Primers flipping in the tray. Aggressive shaking causes primers to flip in the tray and present anvil-down rather than anvil-up. Use a gentle side-to-side rocking motion with the tray held nearly level. If primers are persistently inverting, check whether the tray is correct for your primer size – large primers in a small tray (or vice versa) will flip regardless of technique.
Dial hard to turn. Factory machining oil or small metal shavings from assembly can accumulate in the dial mechanism on new tools. Disassemble the depth adjustment section, clean with a solvent-dampened swab, dry thoroughly, and apply a small amount of dry-film lubricant to the dial threads. Reassemble and verify smooth operation before calibrating.
Primer jams at the tray exit. Primers can get stuck at the point where they transfer from the tray to the seating position if the transfer path has debris or if the primer size doesn’t match the tray. Verify you’re using the correct tray for your primer size. Clean the transfer path with a small brush.
High primers after using the hard stop. If primers consistently seat proud even with the dial advanced several clicks, check that the seating stem matches the primer size being used. A small primer stem in a large primer seating position will not engage the primer properly. Also check that the dial rotation direction is correct – clockwise increases depth, counterclockwise decreases it.
FAQ
Can I use standard press shellholders in this tool?
No – hand priming tools use specialized shellholders shorter than press shellholders. The 12 included shellholders cover the most common caliber families, and the tool is compatible with Lee-style hand-priming shellholders for sizes not in the kit.
Does the hard stop actually prevent high primers?
Yes. Once calibrated correctly, the hard stop physically prevents the handle from advancing further than the set depth. A primer cannot be seated shallower than the hard stop position (assuming the case head is properly seated in the shellholder and there’s no debris in the seating path). This is the tool’s primary value over feel-based hand primers.
How many primers does the tray hold?
100 primers – a full standard sleeve. Load the full sleeve, close the cover, and the tray is ready for 100 primings.
Does it work for 338 Lapua Magnum?
Yes, with the correct shellholder. 338 Lapua Magnum cases use a large primer pocket and require a shellholder matched to the .588-inch case head. Verify which included shellholder number fits this case head before the first use – it may be one of the less common numbers in the set.
How does the depth dial compare to the K-M Primer Deluxe’s threaded stem?
Both provide mechanical depth adjustment. The K-M’s threaded stem adjustment is continuous with no defined click increments – it requires the user to hold the adjusted position while tightening a lock nut. The Frankford’s click-detent dial holds its position without a lock nut but provides only ~0.001-inch resolution per click. The K-M’s single-feed design means individual primer placement and tactile monitoring of each case; the Frankford’s tray design means faster loading with mechanical consistency. For benchrest single-feed precision: K-M. For tray-speed with hard-stop consistency: Frankford.
Can I use this for both large and small primer calibers in the same session?
Yes, but you need to swap the seating stem assembly and shellholder when changing between large and small primers. The swap takes 2-3 minutes. Many reloaders prime all cases of one primer size first, then swap and run all cases of the other size, rather than switching back and forth within a session.
What’s the recommended seating depth target?
0.003-0.005 inches below flush for all applications. Primers seated at this depth have the anvil in full contact with the pocket floor, ensuring consistent, full primer initiation on every firing pin strike.
Conclusion
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool solves the hand primer’s fundamental problem: variable depth from variable hand pressure. The micrometer depth dial and hard stop combination removes the human-feel variable from primer seating and replaces it with a mechanical stop that enforces the same depth on the first primer and the hundredth primer in the same session. For precision rifle loading where ES consistency is tracked, for reloaders with hand conditions that affect grip consistency, and for multi-caliber benches where the included 12-shellholder set removes accessory cost barriers across all common calibers – the Frankford Perfect Seat is the hand primer that addresses these specific requirements.
Its limitations are real: the 2.8-pound weight is noticeable at very high session volumes, depth re-calibration is required when changing brass lots, and it still requires shellholders. For reloaders whose sessions regularly exceed 500 primers, a bench-mounted tool handles the volume more comfortably.
Choose the Frankford Arsenal Perfect Seat if you want mechanically enforced primer seating depth consistency rather than feel-based depth control, load multiple calibers covered by the included 12-shellholder set, and need a portable self-contained precision priming solution that works away from the bench.
Choose the RCBS Universal Hand Priming Tool instead if no-shellholder universal jaw convenience is the priority and feel-based depth control is adequate for your loading goals.
Choose the K-M Primer Deluxe Hand Priming Tool instead if maximum tactile feedback in single-feed operation is the priority for benchrest-level primer discipline, and production speed is secondary to feel quality.
Choose the Forster Co-Ax Bench Priming Tool instead if sustained high-volume sessions require bench-mounted support, universal jaw coverage without shellholders is needed, and portability is not a requirement.
Choose the RCBS Automatic Bench Priming Tool instead if high-volume production with minimal interruptions and standard shellholder compatibility are the priorities at a bench-mounted scale. The Hornady Versa-Prime Bench Priming Tool and Lyman Accu-Prime Manual Bench Priming Tool are additional bench-mounted alternatives for reloaders in those respective ecosystems.
