Our .45-70 ammunition is externally identical to SAAMI spec .45-70 ammo, but internally it generates far more power and pressure. While it will fit into any .45-70 firearm, it is not safe in every .45-70 firearm.
Approved firearms for this high-pressure load include:
- All Marlin 1895 iterations made since 1972 (Model 336 actions chambered in .45-70)
- All Browning 1885 and 1886 copies
- Rossi Rio Grande
- New England Arms Handi Rifle
- T/C Encore
- All falling block actions made of modern steel (e.g., Ruger #1 and #3)
- Shiloh, Christian, and Pedersoli Sharps
- Henry Lever Action Rifles
- All Winchester 1886 iterations made since 1915
- CVA Centerfire Rifles
- All Siamese Mauser bolt actions
Warning: Never use this ammo in any original or reproduced Trap Door action. The design is far too weak to handle the pressures generated by this load.
We use only factory stock firearms to record published velocities, ensuring that our data reflects true, real-world performance—not exaggerated velocities from extra-long laboratory test barrels.
