While taking advantage of state of the art testing equipment, this high performance ammunition by Underwood is field tested using popular, real firearms that customers are most likely to own out in the real world with all the elements you would experience. If for some reason Underwood Ammunition fails to meet performance expectations, Underwood stands by their product 100% and will make sure the customer is satisfied with every purchase. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Hard cast flat nose bullets are non-expanding, powerfully penetrative bullets that are designed with your woods defense needs in mind; whether fending off wild hogs or black bears, the hard cast flat nose bullets are consistently effective in taking down any wild animals that you may encounter. In contrast to the round nose non-expanding bullets, the flat nose bullets are able to pierce through dense bodies of mass while maintaining their nose forward position, which is optimal for maximum penetration. All non-jacketed lead bullets, whether it may be cast, hard cast, wad-cutter, etc. “smoke” to some degree due to the wax/lube needed in the manufacturing process. With the high performance and velocity we achieve it is nearly impossible to stop this from happening. Higher chamber pressures, higher velocities, and higher temperatures mean more smoke in this case. All of Underwood Ammo rounds utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

Owner of Buffalo Bore Tim Sundles on 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

Please note that this ammunition is not intended for older guns. It is made for modern firearms only, as some of the ammunition could damage older and weaker firearms. 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.

Buffalo Bore Dangerous Game ammunition is a line of mono-metal,  non-expanding, dangerous game loads. These “Dangerous Game” (DG) loads are super high quality, very powerful, and will live up to their namesake. Mono-metal bullets have a few advantages (a couple of disadvantages too) over typical non-expanding hard cast bullets. These advantages may or may not be meaningful to each individual, depending on your usage. The advantages are that they are cleaner burning/firing than hard cast bullets. Also, hard cast bullets can smear their nose profile when they hit large bones at close range/high velocity. When the flat nose smears and changes shape, it can impact straight line penetration. The disadvantages are cost and case capacity issues, mono-metal bullets made of copper or brass alloys are lightweight for their length.

Buffalo Bore loads their ammunition with the highest quality components available to maximize the performance of the ammunition. This ammunition is safe to use in all modern firearms that are in proper working condition. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
