ITEM 8B


PRESS RELEASE FOR BUFFALO BORE 45-70 MAGNUM-LEVER GUN (ITEMS 8A, 8B, 8C, 8D, and 8E)

Our 45-70 ammunition 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 into ANY 45-70 firearm but is not safe in every 45-70 firearm. 

Its use should be limited to the following firearms:

All Marlin 1895 (1895 Marlins are all model 336 actions, chambered in 45-70) 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 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.


Never use this ammo in ANY original or reproduced "Trap Door" action as the design is far too weak.

We use only factory stock firearms in recording published velocities, so you get true, actual field velocities with our ammo -- not exaggerated long laboratory test barrel velocities.

Item 8B (405gr. JFN expander)


?  2002 fps -- Marlin 1895, 22-inch barrel
?  1955 fps -- Marlin 1895 Guide Gun, 18.5-inch barrel


Many a Grizzly Bear, Cape Buffalo, Bison and other dangerous game have fallen to our 45-70 loads since we began 45-70 production 1999. Below is an idea of what type of game these loads were designed for.

Item 8B -- the bullet utilized expands to an inch or more in diameter at our velocities, and hence penetration is limited to about two feet in flesh and bone. This is the single most effective hog and black bear load ever devised in 45-70. I don't use it on animals weighing more than 800 lbs as it won't give adequate penetration at bad angles for animals larger than 800 lbs. If you'll limit yourself to broadside (double lung) and CNS hits, this load will work on 2,000 lb animals.
