The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is widely recognized as a benchmark in the hand-priming category, engineered to provide reloaders with a level of precision usually reserved for expensive bench-mounted stations. For many enthusiasts, the transition from press-mounted priming to a hand-held unit is driven by a desire for better tactile feedback and the convenience of priming cases away from the loading bench. However, the common drawback of manual tools is the risk of inconsistent seating depths or crushed primer cups. The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool addresses these mechanical shortcomings through a specialized adjustable dial and a robust “hard stop” system that ensures every primer is seated to the exact same depth regardless of how much pressure is applied to the lever.
Constructed for high-volume use and precision accuracy, the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is part of the brand’s flagship Platinum Series, which prioritizes durability and user-centric features. Unlike economy-grade tools that rely on plastic linkages and thin aluminum housings, this tool uses heavy-duty materials to eliminate flex. This rigidity is critical for long-range shooters loading calibers like 6.5 Creedmoor or 308 Winchester, where consistent primer ignition is a foundational requirement for shrinking group sizes.
- Tool Category – Hand-Held Primer Seating Station
- Operation Type – Squeeze-Lever with Adjustable Depth Dial
- Mechanical Standout – Integrated micrometer-style depth adjustment in 0.001-inch increments
Best For: Serious precision reloaders who want a portable priming solution that offers the repeatable depth control of a bench tool, while also providing enough durability to handle large batches of military brass.
Technical Specifications & Market Pricing
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is built to stand up to decades of service, which is reflected in its heavy-duty technical profile.

| MPN | 110006 |

Pricing Analysis
While the MSRP for the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool sits at $115.99, it is frequently available through major retailers for between $75.00 and $82.00. This pricing positions it as a mid-to-high tier option. When compared to basic entry-level tools like the Lee New Auto Prime Hand Priming Tool, the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool represents a significantly higher investment. However, the value is found in the “all-in-one” nature of the kit. The tool includes 12 proprietary shellholders that cover over 600 common calibers and a custom-fitted injection-molded storage case. If a reloader were to purchase a basic tool and then buy 12 individual shellholders for it, the total cost would often exceed the street price of the Frankford kit. Additionally, the ability to control seating depth to 0.001-inch is a feature rarely found at this price point, making it a bargain for those who prioritize match-grade ammunition.
Build Quality, Materials, and Ergonomics
The first thing most users notice when picking up the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is its substantial weight. At nearly 3 pounds, it is significantly heavier than its competitors. This heft is due to the die-cast zinc body and the use of substantial steel components in the internal drive train. This construction choice ensures that the tool does not “give” or flex when seating stubborn primers into tight pockets, a common issue with plastic or lightweight alloy tools.
Ergonomics and Lever Design
Ergonomics are a primary focus for the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool. While many older hand-priming tools require the use of the thumb to push a vertical plunger, this tool uses a full-grip squeeze lever. This design distributes the effort across the entire hand, significantly reducing fatigue during long sessions of priming hundreds of 45 ACP or 223 Remington cases. The handle is contoured to fit the palm naturally, though users with smaller hands may find the initial reach of the lever somewhat wide.
The Micrometer Depth Dial
The mechanical centerpiece of the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is the depth adjustment dial located at the top of the tool. Each “click” of this dial moves the seating stem approximately 0.001-inch. This allows the reloader to fine-tune the seating depth so that the primer anvil is slightly compressed against the bottom of the primer pocket—a state known as “priming to a crush.” By using the hard stop, the user can squeeze the handle until it bottoms out, knowing that the primer will never be crushed beyond the desired setting. This eliminates the “human error” variable that comes with tools that rely entirely on the user’s “feel.”
Comprehensive Setup, Calibration, and Operation
To maximize the performance of the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool, a specific setup and calibration protocol should be followed.
Initial Assembly and Conversion
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool comes pre-configured for one primer size, but swapping between Small and Large primer systems is quick and requires no tools.
- Remove the clear primer tray and the shellholder.
- Unscrew the thumb-wheel to access the internal seating stem.
- Swap the stem, spring, and guide for the alternative size (both are included in the case).
- Reinstall the thumb-wheel and snap the correct shellholder into place.
Calibration Protocol
For precision results, it is recommended to calibrate the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool whenever changing brands of brass or primers.
- Insert a deprimed case into the shellholder.
- Start with the depth dial at a shallow setting (turned to the left).
- Place a primer in the tray and squeeze the handle.
- Check the depth of the seated primer with a depth gauge or by sliding the case across a flat surface.
- If the primer is proud (above flush), turn the dial to the right by 2-3 clicks and repeat with a new case.
- Once the primer is seated 0.003-0.005 inches below flush, lock the setting. For the rest of the batch, you can simply squeeze the lever to the stop.
Maintenance and Operation Tips
To keep the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool operating smoothly, keep the primer tray and internal stem clear of brass shavings and primer dust. A small drop of dry-film lubricant on the pivot points every 5,000 rounds will maintain the smooth “snap” of the lever action. If you are processing military 5.56 NATO brass, ensure you have used a tool like the Dillon Precision Super Swage 600 Primer Pocket Swager or the Frankford Arsenal Platinum Series Hand Depriming Tool to remove the primer pocket crimp first. The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is strong, but seating primers into an un-swaged crimp can cause inconsistent depths or dented primers.
Internal Brand Hierarchy
Within the Frankford Arsenal ecosystem, the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool sits as the premium choice for hand priming. It is designed to complement the Frankford Arsenal M-Press and the X-10 Progressive Press. While progressive presses offer high speed, many shooters prefer the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool for their precision rifle work to ensure that the priming step is handled with individual attention.
Compared to the standard Frankford Arsenal Hand Priming Tool (non-Platinum), the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool offers significantly higher durability and the critical addition of the micrometer depth dial. For most reloaders, the “Platinum” version is the preferred choice because it solves the most common complaint with hand-held tools: the lack of a repeatable mechanical stop.
Competitive Market Analysis
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool competes in a market that ranges from $25 budget tools to $200 boutique instruments.
Deep Dive into 4 Competitors
- RCBS Universal Hand Priming Tool: This is a major rival. The RCBS tool uses a universal jaw system that requires no shellholders, which is a major convenience. However, it lacks a depth-adjustment dial, meaning seating depth is controlled entirely by the user’s hand pressure.
- Lee New Auto Prime Hand Priming Tool: This is the budget-friendly alternative. It is very light and inexpensive, but it uses proprietary shellholders and has a significantly shorter lifespan due to its plastic and light-alloy components. It lacks the “hard stop” of the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool.
- K&M Primer Deluxe Hand Priming Tool: This is a boutique tool favored by benchrest shooters. It offers extreme tactile feel but is a single-feed tool (no tray). The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool offers similar depth precision but with the much higher speed provided by the 100-round primer tray.
- Lyman E-ZEE Prime Universal Hand Priming Tool: Like the RCBS, this tool focus on ease of use with universal shellholder compatibility. It is a solid mid-range tool but doesn’t offer the granular depth control that the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool provides for match-grade consistency.

Real-World Feedback & Troubleshooting
Real-world feedback for the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is largely positive, with users frequently calling it a “tank” of a tool. It is particularly praised by reloaders with arthritis or hand pain, as the full-grip lever is much easier to operate than thumb-style plungers. However, no tool is without its quirks.
Pros
- Virtually impossible to “high-prime” once the dial is set.
- The included shellholder set saves the user $50-70 in additional purchases.
- Excellent tactile “click” when the primer hits the bottom of the pocket.
Cons
- Heavy weight can cause hand fatigue during extremely long sessions (500+ rounds).
- The primer tray cover can sometimes be tight and difficult to slide on and off when new.
Troubleshooting Technical Quirks
- Inconsistent Seating: This usually happens if there is debris under the shellholder. Workaround: Remove the shellholder and ensure the seating area is clean. Even a single flake of gunpowder can throw off the depth by several thousandths.
- Primer Jams: If primers are flipping in the tray, ensure you are holding the tool at a slight upward angle. Workaround: Do not shake the tool violently to move primers; a gentle side-to-side motion is sufficient to feed the next round onto the ram.
- Dial Getting Stuck: Some users have reported the adjustment dial becoming hard to turn. Workaround: Disassemble the top section and clean any factory machining oil or metal shavings, then apply a tiny amount of dry lube.
FAQ (Extended)
Q: Can I use standard press shellholders in the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool?
A: No. Hand priming tools generally use shorter, specialized shellholders. However, the Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool includes the 12 most common sizes, which covers the vast majority of calibers. It is also compatible with Lee-style hand-priming shellholders if you need a size not included in the kit.
Q: Does this tool work with both Large and Small primers?
A: Yes. The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool comes with all necessary parts to convert between large and small primers, including the trays, springs, and seating stems.
Q: Is it safe to use this tool with Federal primers?
A: Yes, it is compatible with all major primer brands including Federal, CCI, and Winchester. As with all priming, always wear safety glasses and point the case mouth away from you.
Q: How many primers does the tray hold?
A: The tray is designed to hold a full 100-round sleeve of primers.
Q: Can I use this for 50 BMG?
A: No. 50 BMG is far too large for any standard hand-priming tool and requires specialized equipment.
Q: Is the depth adjustment permanent?
A: The dial has distinct clicks that hold it in place during use, so it won’t drift. However, you should check it periodically if you are running very large batches.
Q: What if I break a part?
A: Frankford Arsenal is known for excellent customer service and typically offers replacement parts for their Platinum Series tools.
Q: Does it work with 338 Lapua Magnum?
A: Yes, provided you use the correct shellholder (usually a #14 or #4 depending on the brand), the tool has enough leverage to seat large magnum primers into these big cases.
Conclusion & Expert Verdict
The Frankford Arsenal Platinum Series Perfect Seat Hand Priming Tool is an over-engineered solution for one of the most critical steps in the reloading process. By providing a mechanical hard stop and a precision adjustment dial, it removes the guesswork that often leads to inconsistent primer depths. While it is heavier and more expensive than entry-level options, the inclusion of a full shellholder set and the match-grade results it produces make it a top-tier choice for any serious reloader. It successfully combines the speed of a tray-fed hand tool with the precision of a bench-mounted station.
Expert Pro Tip: When you find the “perfect” seating depth for your favorite caliber, such as 308 Winchester or 6.5 Creedmoor, count the number of clicks from the fully-bottomed position and write it on the inside of the storage case. This allows you to return to the exact same seating depth in seconds the next time you load that caliber, ensuring absolute consistency across different reloading sessions.
