Item # 292547 Style BFF-4B/20 UPC 651815004228 Condition New Manufacturer [Buffalo Bore](https://www.kygunco.com/brand/buffalo-bore) Units Per Box 20 Caliber 44 Rem Mag Weight 1.42 lb Item 4B (300gr. JFN) is designed for super deep penetration at revolver speeds but will mushroom and penetrate less deeply at rifle speeds. At handgun velocities, you can expect approximately 3 feet of penetration in muscle and bone. At rifle velocities, expect roughly 2 feet of penetration. At handgun speeds, this bullet behaves similarly to Item 4A in living tissue. The higher velocities produced by longer rifle barrels cause the bullet to mushroom, creating a larger diameter wound channel. However, the increased frontal area of the mushroomed bullet reduces penetration depth. Below are velocity measurements from over-the-counter revolvers and rifles: - 1,330 fps – Ruger Super Blackhawk, 6-inch barrel - 1,334 fps – Ruger Redhawk, 5.5-inch barrel - 1,770 fps – 1894 Marlin, 18.5-inch barrel Item 4B is recommended for use in all steel revolvers and rifles currently on the market. It is **NOT** suitable for scandium or aluminum alloy revolvers. ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
