Introduction
The Federal Power-Shok has been available since the 1960s, and its market position has not changed in that time: it is the most affordable jacketed soft-point in Federal’s lineup, designed for hunters who want reliable deer-killing performance at the lowest reasonable price per bullet.
There is no pretense here that the Power-Shok is Federal’s most technically sophisticated bullet. The same company makes the Federal Fusion with electrochemical bonded construction and the Federal Trophy Bonded with premium grooved-shank bonding and a polymer tip. The Power-Shok is the entry point – a conventional cup-and-core soft-point with a flat base, a cannelure, and a lead soft-point nose. It is built to work reliably on deer-sized game at hunting ranges and to be priced so that a hunter loading 200 rounds for a season does not need to think twice about cost.
What distinguishes the Power-Shok from similar budget designs like the Remington Core-Lokt and Sierra Pro-Hunter is primarily availability and Federal brand identity, not construction superiority. All three are flat-base cup-and-core soft-points with comparable BC ranges and similar terminal performance on deer at normal hunting ranges. The honest assessment is that at 150 yards on a broadside whitetail, a hunter cannot tell which one was in the case by the outcome.
The caliber range runs from .224-inch to .458-inch, covering 223 Remington varmint loads through 45-70 Government big game territory. Weights span 55 to 300 grains. That breadth matches the Sierra Pro-Hunter and exceeds the Remington Core-Lokt, making the Power-Shok one of the most widely available conventional hunting bullets for unusual or older cartridges that premium component manufacturers may not cover.
Technical Characteristics
The Power-Shok’s construction is straightforward cup-and-core. Federal uses a lead core pressed into a copper-alloy jacket cup, with the jacket thinned at the nose to expose a soft-point tip that initiates expansion on impact. There is no special bonding process, no mechanical interlock like the Remington Core-Lokt‘s tapered jacket, and no polymer tip. What you have is the fundamental hunting bullet construction that has been in use since jacketed bullets became standard in the early twentieth century.
The soft-point nose exposes enough lead to initiate expansion at impact velocities from 1,800 fps upward. Expansion target is 1.5x to 2x original diameter, identical to what Federal specifies for the Federal Fusion and other designs in the lineup. The difference is that the Power-Shok achieves this through jacket thinning alone, without bonding – which means weight retention (typically 50 to 70% under stress) is lower than bonded alternatives when impact conditions are severe. At standard hunting velocities on broadside shots through the lungs, this rarely matters. On a shoulder blade hit from a 300 Winchester Magnum at close range, the lack of core bonding can mean the jacket and core part ways and the bullet delivers less total energy than intended.
The flat base is standard across most Power-Shok weights. It is not a design flaw – flat-base bullets offer slightly better stability at muzzle exit and are simpler to manufacture than boat-tail designs. The tradeoff is higher base drag at distance, which limits the Power-Shok’s aerodynamic efficiency past 200 yards compared to boat-tail designs in the same caliber and weight.
One notable data point from the ballistics table: the 140-grain .264-inch Power-Shok carries a G1 BC of 0.439. This figure is higher than most other Power-Shok weights and reflects a boat-tail spitzer or semi-spitzer design in the 6.5mm variant rather than the flat-base construction typical of the rest of the lineup. Federal offers several Power-Shok variants in different profile types – round-nose, soft-point, and hollow-point – and the 6.5mm 140-grain appears to be among the more aerodynamically efficient configurations. Verify the specific profile of the variant you are ordering before building load data around a BC figure.
The cannelure is present across the lineup. It provides a reliable seating depth reference for volume loading, allows crimp application for tubular-magazine rifles and semi-automatic platforms, and contributes to consistent bullet position in the case during magazine handling under recoil.
Jacket consistency and lot-to-lot dimensional variation are the areas where the Power-Shok is most likely to trail the Sierra Pro-Hunter and Remington Core-Lokt. Federal’s quality control on the Power-Shok is adequate for hunting use, but handloaders seeking the tightest possible groups should expect to find more variation between lots than with Sierra or Hornady component bullets. For hunting accuracy at 200 yards, this level of variation is inconsequential. For load development targeting sub-MOA benchrest-style consistency, it is worth noting.
Disclaimer: Reloading is an inherently dangerous activity. Always consult current published load data from reputable sources (Federal, Hodgdon, Hornady, Lyman) before loading any cartridge. Start at minimum charges and work up carefully while watching for pressure signs. Never exceed maximum published loads. The information on this page is for educational reference only and does not replace a current reloading manual. Note that 45-70 Government loads using the 300-grain Power-Shok must be matched to your specific action type – Trapdoor Springfield, lever-action, and modern single-shot platforms each have different maximum pressure limits. Never use loads intended for a stronger action in a weaker one.
Ballistics and Performance
G1 BCs from 0.165 to 0.439 span a range that reflects the significant variation in profiles across the Power-Shok lineup. The low end of that range – BC 0.165 for some light .224-inch variants – represents round-nose or hollow-point configurations rather than the spitzer soft-points, and those figures drop faster at distance. The 0.439 at the high end is the 140-grain 6.5mm which, as noted above, appears to use a more aerodynamic profile.
For practical hunting ballistics, the most representative Power-Shok figures are the 100-grain .243-inch at BC 0.355, the 130-grain .277-inch at BC 0.367, and the 150-grain .308-inch at BC 0.266. The .243-inch and .277-inch figures are competitive with the Sierra Pro-Hunter and Remington Core-Lokt at comparable weights. The 150-grain .308-inch at BC 0.266 is identical to the Remington Core-Lokt 150-grain and comparable to the Sierra Pro-Hunter 150-grain at 0.266 – these three bullets are effectively aerodynamic equals at this caliber and weight.
From a 308 Winchester at 2,820 fps, the 150-grain Power-Shok drops approximately 6.5 inches at 200 yards and around 19 inches at 300 yards with a 100-yard zero. In a 10 mph crosswind, it drifts roughly 3.5 inches at 200 yards and 8 inches at 300 yards. These are identical numbers to what the same-weight Remington Core-Lokt produces, which underscores that at this performance level the bullets are interchangeable in field terms.
The 180-grain .308-inch Power-Shok at BC 0.382 is an interesting outlier – the BC is notably higher than the comparable Remington Core-Lokt 180-grain at BC 0.254, suggesting a different profile geometry for this weight. If accurate, this makes the 180-grain Power-Shok somewhat more aerodynamically efficient than the Core-Lokt at this weight, though both remain flat-base designs with practical range limitations around 300 yards for hunting purposes.
The 300-grain .458-inch at BC 0.225 and SD 0.204 is the lineup’s heavy end for 45-70 Government applications. SD 0.204 is modest for a hunting bullet intended for large game – it provides adequate penetration on deer and black bear but is marginal for the heaviest use cases like brown bear or very large bull elk. The Sierra Pro-Hunter 400-grain .458-inch at SD 0.272 provides significantly deeper penetration for those scenarios. The Power-Shok 300-grain is a reasonable deer and elk load at 45-70 Government velocities appropriate to the specific action type.
Accuracy runs 0.8 to 1.5 MOA in typical hunting rifles – somewhat behind the Sierra Pro-Hunter (0.8-1.5 MOA) and Sierra GameKing (0.5-1.0 MOA), and comparable to the Remington Core-Lokt at the same performance tier.

Comparison Bullets
The Power-Shok’s honest comparison set is other budget-to-mid flat-base conventional soft-points. At this price and construction level, aerodynamic refinements and premium terminal engineering are not the differentiators – reliability, availability, and price per round are.
The Remington Core-Lokt is the most direct competitor and the one with the best claim to outperforming the Power-Shok at this tier. The Core-Lokt’s tapered jacket creates a mechanical interlock between the core and jacket that the Power-Shok’s plain cup-and-core construction does not replicate, giving the Core-Lokt better weight retention (65-80%) under high-velocity impact on heavy bone compared to the Power-Shok (50-70%). Both bullets overlap substantially on BC, weight range, and caliber coverage. On a broadside deer shot inside 200 yards, the practical difference between them is negligible. On a shoulder shot at magnum velocity, the Core-Lokt is marginally more reliable. For the majority of deer hunting scenarios, the choice between them comes down to price and which one groups better in your specific rifle.
The Sierra Pro-Hunter is the other direct flat-base soft-point comparison. Sierra maintains tighter manufacturing tolerances than Federal on the Power-Shok, which typically translates to slightly better accuracy and more consistent lot-to-lot performance. The Pro-Hunter covers a wider weight range (up to 400 grains in .458-inch versus the Power-Shok’s 300 grains), which matters if you are loading for a cartridge or bullet weight the Power-Shok lineup does not offer. The Pro-Hunter costs marginally more per bullet. For handloaders who care about squeezing the last fraction of an MOA from their hunting loads, the Pro-Hunter is the more consistent component.
The Sierra GameKing is the step up in aerodynamic performance. The boat-tail base and higher BCs (0.185-0.517) give the GameKing meaningfully better trajectory and wind resistance past 250 yards compared to the Power-Shok. If your hunting consistently involves shots at 300 yards or beyond, the GameKing’s BC advantage justifies its modest price premium over the Power-Shok. Inside 200 yards, the difference is small enough to ignore.
The Hornady InterLock covers similar price territory with a mechanical ring that interlocks the core to the jacket – a core-retention mechanism the Power-Shok lacks. Like the Core-Lokt, the InterLock provides better core retention than the Power-Shok at high impact velocities, at a price point that remains accessible. For hunters who want a core-retention mechanism without paying bonded bullet prices, the InterLock or Core-Lokt is a better choice than the Power-Shok.
Against the Federal Fusion – which is Federal’s own bonded step-up from the Power-Shok – the Fusion’s electrochemically bonded core provides 95%+ weight retention versus the Power-Shok’s 50-70%. The Fusion costs more, but for hunters loading for elk, moose, or heavy game where the bonded advantage matters, the price difference is justified. For deer inside 250 yards where the core-retention difference rarely affects outcomes, the Power-Shok’s lower cost is the stronger argument.
Comparison Table – Budget and Mid-Range Soft-Point Hunting Bullets
| Bullet | Diameter Range | Weight Range | BC Range | Core Retention | Relative Cost |
|---|---|---|---|---|---|
| Federal Power-Shok | .224-.458 | 55-300 gr | 0.165-0.439 | 50-70% (pressure fit) | Budget |
| Remington Core-Lokt | .224-.375 | 55-250 gr | 0.200-0.300 | 65-80% (tapered jacket) | Budget-Mid |
| Sierra Pro-Hunter | .224-.458 | 55-400 gr | 0.185-0.310 | 55-75% (pressure fit) | Budget-Mid |
| Hornady InterLock | .224-.458 | 55-400 gr | 0.200-0.360 | 65-80% (InterLock ring) | Budget-Mid |
| Federal Fusion | .224-.338 | 90-200 gr | 0.276-0.520 | 95%+ (bonded) | Mid |
Applications and Practical Aspects
The Power-Shok’s strengths are breadth of caliber coverage, low cost, and wide retail availability. Here is how the different weights map to hunting applications, with honest context about where the bullet’s limitations begin to matter.
Varmints and small game (.224-inch, 55 grains): The 55-grain Power-Shok at BC 0.222 and SD 0.157 is a functional varmint round from 223 Remington or 222 Remington at ranges inside 200 yards. Beyond that distance, purpose-built varmint bullets like the Hornady V-MAX, Sierra BlitzKing, or Sierra Varminter are significantly better aerodynamic choices with more explosive terminal expansion on small targets. The 55-grain Power-Shok is best suited to close-range coyote work where long-range BC matters less than low cost per round. Powders like Hodgdon Varget, Hodgdon CFE 223, and Hodgdon H335 are well-matched to this weight in 223 Remington.
Light deer and antelope (.243-inch, 80-100 grains): Both .243-inch Power-Shok weights are capable deer and antelope bullets in 243 Winchester. The 80-grain at SD 0.194 is the lighter option for antelope and lighter deer; the 100-grain at SD 0.242 is better suited to larger deer and borderline elk at close range. BC 0.355 for the 100-grain is reasonably competitive with the Sierra Pro-Hunter 100-grain at BC 0.276 – the Power-Shok 100-grain .243 appears to use a more pointed profile, giving it an aerodynamic edge at distance over the Pro-Hunter in this specific weight. Powders like Hodgdon Varget, IMR 4064, and Hodgdon H4350 work well with both .243-inch weights.
Deer, elk (6.5mm, 140 grains): The 140-grain .264-inch Power-Shok at BC 0.439 and SD 0.287 is the most aerodynamically capable entry in the lineup at this weight. In 6.5 Creedmoor, 260 Remington, or 6.5×55 Swedish Mauser, SD 0.287 gives meaningful penetration on deer and lighter elk. Hodgdon H4350, Alliant Reloder 16, and IMR 4064 are standard powder choices for 140-grain 6.5mm loads.
Deer, antelope (.277-inch, 130 grains): The 130-grain Power-Shok at BC 0.367 and SD 0.242 in 270 Winchester is a well-validated deer and antelope load. BC 0.367 is competitive with Sierra Pro-Hunter 130-grain at BC 0.242, giving the Power-Shok a genuine aerodynamic advantage at this weight in 270 Winchester. For shots inside 250 yards the difference is small, but past 300 yards the Power-Shok 130-grain holds velocity better than the Pro-Hunter in the same weight. Hodgdon H4350, IMR 4350, and Alliant Reloder 19 are standard choices for this combination.
Deer, black bear (7mm, 140 grains): The 140-grain .284-inch Power-Shok at SD 0.248 in 7mm-08 Remington or 7×57 Mauser is a functional deer and black bear load at moderate range. BC 0.248 is the lowest in the table for this weight class, which limits effective range compared to higher-BC options. Inside 200 yards this is not a practical concern for deer. Hodgdon Varget, IMR 4064, and Alliant Reloder 15 are appropriate powders.
Standard 30-caliber deer and elk (.308-inch, 150-180 grains): The 150-grain .308-inch at SD 0.226 covers standard deer hunting in 308 Winchester and 30-06 Springfield reliably inside 250 yards. The 180-grain at SD 0.271 and BC 0.382 adds penetration for elk and large deer in 30-06 Springfield – notably, BC 0.382 is higher than the Remington Core-Lokt 180-grain at 0.254, which if accurate makes the Power-Shok 180-grain the more aerodynamically capable of the two at this weight. For the 150-grain in 308 Winchester, powders like Hodgdon Varget, IMR 4895, Hodgdon H4895, and Alliant Reloder 15 are well-documented choices. For the 180-grain in 30-06 Springfield, Hodgdon H4350, IMR 4350, and Alliant Reloder 19 are standard.
Elk, moose (.338-inch, 200 grains): The 200-grain .338-inch Power-Shok at BC 0.288 and SD 0.250 in 338 Winchester Magnum is a functional elk and moose bullet inside 250 yards. SD 0.250 provides adequate penetration on elk-sized game at realistic hunting ranges. The plain cup-and-core construction means this bullet relies on impact velocity and jacket geometry for weight retention – at close range 338 Winchester Magnum velocities on heavy shoulder bone, consider stepping up to the Federal Fusion or Federal Trophy Bonded for more reliable core retention in those conditions. Hodgdon H4831SC, Alliant Reloder 22, and IMR 4831 are appropriate powders.
Large game in 45-70 (.458-inch, 300 grains): The 300-grain .458-inch Power-Shok at SD 0.204 in 45-70 Government is a deer and elk load for hunters using lever-action or single-shot rifles. The critical note here applies regardless of which bullet you choose for 45-70 Government: this cartridge operates across three distinct pressure tiers and the appropriate load depends entirely on your action. Original Trapdoor Springfield actions are limited to approximately 20,000 PSI – only Trapdoor-specific load data is safe. Standard lever-action rifles like the Marlin 1895 operate at approximately 40,000 PSI – use data labeled for lever-action or modern-strength actions at this tier. Modern strong single-shot rifles like the T/C Encore handle up to approximately 60,000 PSI. Never use a higher-pressure load in an action rated for a lower tier. Powders appropriate for 45-70 Government lever-action and single-shot loads with 300-grain bullets include Hodgdon H4198, IMR 3031, and Hodgdon Leverevolution.
Reloading
The Power-Shok is among the most straightforward components to reload. Its conventional profile is compatible with any standard die set, and load data for comparable conventional soft-points in the same weight and caliber from any major manual applies without modification.
Primers: Standard large rifle primers cover all 30-caliber and larger applications. CCI 200, Federal 210, Winchester WLR, and Remington 9-1/2 are reliable choices. For smaller cartridges in 223 Remington and 243 Winchester range, standard small rifle primers CCI 400, Federal 205, and Winchester WSR are appropriate. For 223 Remington in AR-platform semi-automatic rifles, the CCI No. 41 mil-spec primer prevents slam-fire with its harder cup. For 338 Winchester Magnum and other large magnum cases with slow powders, magnum primers CCI 250, Federal 215, or Remington 9-1/2M ensure consistent ignition.
Cases: Standard brass from Remington, Federal, Winchester, and Hornady all work well. Lapua brass is available for 6.5 Creedmoor, 308 Winchester, and 338 Winchester Magnum if you want maximum case consistency for precision loads. For 45-70 Government, Starline brass is widely used and well-regarded. Military surplus brass with crimped primer pockets requires swaging or reaming before repriming. 7.62x54R and 303 British military surplus is often Berdan-primed and not suitable for reloading with standard dies.
Seating Depth: Start at 0.010 to 0.050 inches off the lands and seat to magazine-length constraints for hunting loads. The Power-Shok’s flat base makes it slightly less sensitive to seating depth changes than high-BC boat-tail bullets, which simplifies initial load development. The cannelure provides a consistent reference point for volume loading.
Crimp: Apply a light roll crimp at the cannelure for tubular-magazine rifles like 30-30 Winchester applications, semi-automatic platforms, or any setup where bullet setback under feeding pressure is a concern. For bolt-action hunting rifles, proper neck tension is sufficient.
Barrel Twist: Standard twist rates for each caliber apply across the Power-Shok lineup. 1:12 or 1:14 for 55-grain .224-inch, 1:10 for .243-inch through most .308-inch weights, 1:10 for .338-inch, and 1:14 or 1:16 for the 300-grain .458-inch which is a short, heavy bullet that stabilizes readily in slower twists appropriate for big-bore rifles.

Load data note: Power-Shok load data appears in all major reloading manuals under equivalent conventional soft-point data for the same diameter and weight. Standard published data applies without special modifications. Always start at published minimum charges and work up in 0.5-grain increments while monitoring for pressure signs.
Conclusion
The Federal Power-Shok is what it is: the least expensive jacketed hunting bullet in Federal’s lineup, built on conventional cup-and-core construction, designed to work reliably on deer-sized game inside 250 to 300 yards, and priced to make high-volume loading practical. It does not have a mechanical core lock like the Remington Core-Lokt, it does not have bonded construction like the Federal Fusion, and it does not have the boat-tail aerodynamics of the Sierra GameKing. What it has is availability at virtually every rural sporting goods counter in North America, Federal quality control adequate for hunting use, and a price that makes loading a season’s worth of practice and hunting ammunition financially painless.
Choose the Power-Shok if: you hunt deer inside 250 yards in conditions where long shots are not realistic, you prioritize the lowest possible cost per round for high-volume practice loading, or you need a weight or caliber that other budget bullet manufacturers do not offer – particularly in 45-70 Government or heavier calibers where the Power-Shok lineup extends beyond what some competitors cover. It is also a practical choice for a first handloading project where the goal is learning the process without investing in premium components.
Choose something else if: your hunting involves consistent shots past 300 yards – the Sierra GameKing or Sierra Tipped GameKing offer meaningfully better aerodynamics for open-country hunting. If you want the same price tier but better core retention and tighter manufacturing tolerances, the Sierra Pro-Hunter or Remington Core-Lokt are stronger options within the budget soft-point category. If you hunt elk, moose, or black bear at magnum velocities where core separation from heavy bone is a real risk, step up to the Federal Fusion for bonded construction at a modest price premium. If you are in a lead-free zone, you need a monolithic like the Barnes TSX or Barnes TTSX.
For the application it was designed for – putting deer down reliably inside 250 yards without breaking the loading budget – the Power-Shok does its job.
Disclaimer: Reloading involves inherent risks. Always use current load data from published manuals. Never mix data from different sources for the same load. Start below maximum charges and increase gradually. Wear eye protection at all times. The author and myreloading.com are not responsible for injuries or property damage resulting from reloading or shooting handloaded ammunition. 45-70 Government loads must be matched to your specific action’s pressure rating – Trapdoor, lever-action, and modern single-shot actions have different maximum pressure limits and loads are not interchangeable between them.
