Note: Federal Premium has not published muzzle velocity, muzzle energy, or ballistic coefficient data for this specific HammerDown 45-70 300 gr load in any source available at time of writing. The ballistics table below uses a calculated estimate based on comparable 300 gr bonded soft point loads in 45-70 Gov’t from 22″ lever-action barrels. These values are estimates only and will be updated when manufacturer or verified third-party data becomes available.
Ballistics Table
Calculated estimate. Real-world results vary by barrel length, temperature,altitude, and lot. Community submissions will provide measured muzzlevelocity for comparison.
Zeroed at 100 yards. Sight height 1.5″ above bore. Estimated muzzle velocity: ~1850 fps (reference baseline for 300 gr BSP from 22″ lever-action barrel).
| Yards | ~Velocity (fps) | ~Energy (ft-lbs) | ~Trajectory (in) |
|---|---|---|---|
| 0 | ~1850 | ~2281 | -1.5 |
| 50 | ~1718 | ~1966 | +1.4 |
| 100 | ~1594 | ~1692 | 0.0 ← zero |
| 150 | ~1479 | ~1456 | -4.2 |
| 200 | ~1374 | ~1257 | -12.8 |
| 250 | ~1281 | ~1092 | -27.1 |
| 300 | ~1200 | ~959 | -48.5 |
Key takeaway: The 45-70 Gov’t cartridge with a 300 gr projectile is a short- to medium-range hunting round by modern standards. At 100 yards, estimated retained energy is well above 1,500 ft-lbs — adequate for deer and black bear at ethical hunting distances. By 200 yards, trajectory drop exceeds 12 inches, making precise holdover essential and limiting practical hunting range for most shooters. This load is purpose-built for lever-action rifles and performs best inside 150 yards where its heavy bonded bullet delivers maximum terminal effect.
The HammerDown Design and Why It Exists
Federal Premium’s HammerDown line was developed specifically to address a gap in the lever-action ammunition market. Traditional lever-action cartridges like the 45-70 Gov’t were frequently loaded with bullets engineered for bolt-action or single-shot rifles — resulting in inconsistent feeding, crimping, and terminal performance when cycled through tube-magazine lever guns. The HammerDown series uses a nickel-plated case for smooth feeding and reliable extraction in lever-action actions, along with a specially profiled bullet crimp groove designed to withstand the stacking pressures of a tubular magazine without bullet setback.
The bonded soft point bullet construction bonds the lead core to the copper jacket during manufacturing, preventing core-jacket separation on impact — a meaningful advantage when hunting heavier-bodied game like black bear or feral hogs where the bullet may encounter heavy bone before reaching vitals. This is not a general-purpose design repurposed for lever guns; the entire package — case, primer, crimp, and bullet profile — was engineered around the mechanical demands of the lever-action platform.
Best Uses
Good fit:
- Deer hunting at ranges inside 150 yards from a lever-action rifle
- Black bear and feral hog hunting where deep penetration and controlled expansion are priorities
- Mixed woodland and brush hunting where the heavy bonded bullet resists deflection
- Hunters who cycle ammunition through a tube-magazine lever gun and need reliable feeding
- Guides and outfitters who want a dependable, purpose-built lever-action load
Not the right tool for:
- Shots beyond 200 yards, where trajectory drop becomes difficult to compensate without a ranging solution
- Varmint or predator hunting where over-penetration or pelt damage is a concern
- Bolt-action or single-shot rifles where the tube-magazine-specific engineering provides no advantage over standard loads
- Hunters who require lead-free ammunition for compliance with California Condor Zone or other non-toxic regulations — this is a lead-core bullet
- Shooters seeking the highest muzzle velocity in 45-70 — 300 gr loads optimized for lever-action pressure limits will not match the velocity of loads designed for Ruger No. 1 or other strong-action platforms
Reliability Notes
No structured submissions yet.
Based on manufacturer claims and open-source product descriptions, the HammerDown line is specifically engineered for reliable cycling in lever-action rifles with tubular magazines. The nickel-plated brass case is cited by Federal as contributing to smooth feeding and consistent extraction. The bonded construction is described as preventing core-jacket separation across a wide range of impact velocities — a meaningful claim for shots at varied distances. No documented feeding failures, case splits, or primer issues specific to this load appear in publicly available sources at time of writing. All notes above reflect manufacturer claims or open-source information, not structured ballistic or reliability submissions.

Price Reality
- At $62.99 per box of 20, this load costs approximately $3.15 per round
- That positions it in the upper-mid tier for 45-70 factory ammunition — above budget options like Winchester Super-X (~$2.00–$2.50/round) and Remington Core-Lokt (~$1.75–$2.50/round)
- It is comparable in price to Hornady LEVERevolution, which retails in a similar range and represents the most direct competition at this price point
- Buffalo Bore and other specialty heavy loads can exceed $3.50–$4.00/round, making HammerDown reasonably priced for a premium bonded load
- A fair price benchmark for this load is $55–$70 per box of 20; listings above $75 should be considered overpriced unless supply is genuinely constrained
- Case pricing (typically 10 boxes / 200 rounds) is not consistently listed by the manufacturer and will vary by retailer

FAQ
Does the bonded construction in this load make a meaningful difference compared to standard soft points for deer hunting?
For whitetail deer at typical lever-action hunting distances — inside 100 yards — a standard cup-and-core soft point will usually perform adequately, and the bonded construction may not produce a noticeable field difference on broadside shots through the ribcage. The bonded soft point becomes more valuable in scenarios involving heavy bone, angled shots, or heavier-bodied game like black bear, where a non-bonded bullet is more likely to shed its core on impact. If your hunting is exclusively whitetail at close range, the bonded design is a conservative engineering choice rather than a strict necessity. For mixed-use hunting or bear country, it is a meaningful upgrade.
Is this load safe to use in all 45-70 lever-action rifles, including older or vintage Trapdoor Springfield actions?
The 45-70 Gov’t cartridge exists in multiple pressure tiers, and this is a critical safety distinction. Loads designed for modern lever-action rifles like the Marlin 1895 operate at significantly higher pressures than loads safe for vintage Trapdoor Springfield actions. Federal does not publish SAAMI pressure data for this specific HammerDown load, but the HammerDown line is marketed for modern lever-action rifles — it is not labeled as a Trapdoor-safe load. Shooters using vintage or antique 45-70 firearms should consult a qualified gunsmith and use only loads specifically rated for low-pressure Trapdoor actions. Using a modern lever-action load in a Trapdoor Springfield is a serious safety risk.
How does HammerDown compare directly to Hornady LEVERevolution in the 45-70 for hunting purposes?
These two loads represent different engineering philosophies for the same platform. Hornady LEVERevolution uses a polymer-tipped FTX bullet with a higher ballistic coefficient, which reduces trajectory drop at longer ranges and initiates expansion reliably at lower impact velocities — an advantage for shots past 150 yards. The Federal HammerDown uses a bonded soft point, which prioritizes controlled expansion and core retention over flat trajectory, making it a stronger choice when penetration depth matters more than long-range arc. For most lever-action hunting inside 150 yards, the terminal performance difference is modest; the choice often comes down to whether the hunter prioritizes retained weight (HammerDown) or flatter trajectory (LEVERevolution).
Why does Federal market HammerDown specifically for lever-action rifles rather than all 45-70 platforms?
The HammerDown line incorporates several design elements that are specifically beneficial for lever-action tube-magazine rifles: a nickel-plated case for smooth feeding and extraction, a bullet profile and crimp geometry optimized for stacking in a tubular magazine without bullet setback under recoil, and a pressure curve tuned for lever-action bolt-and-carrier timing. These features are not harmful in a bolt-action or single-shot 45-70, but they provide no specific advantage in those platforms. The marketing focus reflects genuine engineering intent rather than pure branding — this is a load that was built around how a Marlin 1895 or Henry 45-70 actually handles and cycles ammunition.
Is this load compliant for hunting in states or zones that require non-toxic (lead-free) ammunition?
No. The Federal Premium HammerDown 300 gr Bonded Soft Point uses a lead-core bullet bonded to a copper jacket. It is not a lead-free projectile and does not qualify as non-toxic ammunition under regulations such as California’s Condor Zone requirements or any other jurisdiction mandating non-lead hunting ammunition. Hunters who need to comply with lead-free regulations should look at copper or copper-alloy monolithic bullet loads — such as Federal’s own Trophy Copper line or Barnes VOR-TX offerings — rather than this load.
