Its use should be limited to the following firearms: All Marlin 1895 (1895 Marlins are simply 336 actions, with a 45-70 barrel screwed on to them) iterations made since 1972, 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 such as the Ruger #1 and #3, Shiloh, Christian and Pedersoli Sharps, all Winchester 1886 iterations made since 1915 and all Siamese Mauser bolt actions.

Owner of Buffalo Bore Tim Sundleson Buffalo Bore 45-70 Mag +P Ammunition:

This is a super powerful 45-70+P loading. It is externally identical to SAAMI spec. 45-70 ammo, but internally it generates FAR more power and pressure. So, our 45-70 ammo will fit/chamber into any 45-70 firearm. HOWEVER, its use should be limited to firearms that are built to take the +P pressures it generates.

We were not able to develop velocities as fast as we’d like because the long-for-weight all copper bullet crowds the limited powder capacity of the 45-70 casing. Still, 2200+ fps is screaming and is powerful and for those that understand the benefits of the all copper Barnes TSX bullet, it is a worthwhile trade off. As an added benefit to many shooters, this reduced velocity also means significant recoil reduction.

As always, we use real world firearms to generate our published velocities. We feel the industry wide duplicitous practice of generating advertised velocities from extra long laboratory barrels is dishonest to the customer as he/she will not be able to duplicate those velocities in the real world, where it matters.

• 2215 fps — Marlin 1895, 22 inch barrel
• 2201 fps — Marlin 1895, 18 inch barrel

Both the Magnum and Lower Recoil versions of this ammunition are designed to kill game animals in the 1500 lb. class and yes this 350gr. JFN bullet out-penetrates the 405gr. JFN bullet, due to its tougher construction and therefore smaller mushroom—expect around 48 inches of penetration in living flesh and bone. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

This is a very hard cast bullet and is not designed to mushroom at intended impact velocities. It has been known to penetrate up to six feet in game animals and is therefore useful for animals up to 2,500 lbs.
