Product Information

Buffalo Bore loads their ammunition up to maximum SAAMI specifications, which delivers devastating performance on a wide range of game. Please note that this ammunition is not intended for older guns. It is made for modern post war firearms only, as some of the ammunition could damage older and weaker firearms. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Owner of Buffalo Bore Tim Sundles on Heavy 45 Colt Ammunition:

We knew that we could develop a couple standard pressure 45 colt loads that would feature a 255gr. Gas checked soft cast bullet at around 1,000 fps or a 200gr. Jacketed Hollow Point at around 1,100fps. We wanted loads that were substantially more powerful than today's weenie loads, but that could be fired in ANY 45 colt firearm.

Both of these 45 colt loads are designed to be a heavy loading, yet be within standard (SAAMI) pressure. As such, both of these 45 colt loads are safe and recommended to be used IN ANY post-war 45 colt that is in normal working condition.

These loads are indeed heavy 45 colt loadings. You can fire them in any post-war firearm that is in normal working condition chambered for 45 colt without reservation. These loads will turn your Colt SAA or clone into a powerful carry gun. The cast load (item 3E) is gas checked and will not substantially lead your barrel.

See the below velocities.
