BUFFALO-BARNES LEAD FREE 45-70 MAG. +P
300 gr. TSX-FN (2350 fps)
20 Round Box
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.
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, Henry Lever Action Rifles, all Winchester 1886 iterations made since 1915, CVA Centerfire Rifles and all Siamese Mauser bolt actions.
This all copper expanding 300gr. TSX long-for-weight bullet will penetrate about as deep as they typical 350+gr. lead core expanding bullet, yet it gives the benefits of a lighter bullet, which means it recoils less and gives flatter trajectories.
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
Many shooters do not understand why the 45-70 needs very little barrel length to obtain maximum velocities. As evidenced by the above velocities, ANY straight walled (not a bottle neck case such as the 06 or any number of casings that have a shoulder) case that uses relatively fast burning rifle powders, will generate all the velocity possible in barrels much shorter than bottleneck chamberings.
