Buffalo Bore Ammunition 32B/20 45 Auto Rim +P 200GR JHP 20Box/12Case
You've been asking for a couple +P 45 AUTO RIM loads for a long time, so by popular demand, here they are. Both loads are using high quality Starline brass. We've also incorporated a flash suppressed powder so you can shoot in the dark without blinding yourself and this is important because over 95% of all civilian shootings in the USA occur in low light when the criminal element is at work. Both of these loads are the equivalent of +P+ 45 ACP ammo or as it is also known, 45 Super. These are very stout loads, but will not harm modern 45 ACP revolvers, nor will these loads harm any post war 45 ACP revolvers. Feel free to safely shoot these loads in any post war 45 ACP revolver that is in normal good operating condition.
Check out the below velocities fired from personal real world revolvers, NOT test barrels. You'll notice that the new S&W 4 inch Mt. Gun gives speeds almost as fast as the older S&W revolvers with 5.5 and 6.5 inch barrels. This is NOT a typo. It simply shows that the new S&W revolvers are made to much tighter tolerances than the older S&W revolvers and therefore give higher velocities per inch of barrel. Also, we are aware that the 1937 manufactured model 1917 we used as a test gun, (see below velocity chart) is not post war.
Item # 32B - 200gr. Jacketed Hollow Point bullet
S&W Mountain Gun, 4 inch bbl = 1197 fps
S&W Model 325 (scandium) 2.5 inch bbl = 1080 FPS
S&W Model 1917 (1937 production) 5.5 inch bbl = 1203 FPS
S&W 1955 Target (25-2) 6.5 inch bbl = 1249 FPS
Item # 32B was designed for expansion and massive terminal damage, with less than 1/2 the penetration of item # 32A in flesh and bone. Expect about 14 inches of penetration from this load on live flesh and bone.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 45 Auto Rim is a rimmed version of the 45 ACP introduced in 1920 for revolvers chambered for the 45 ACP cartridge. The 1917 Colt revolver in 45 ACP was a World War I accommodation due to inadequate supplies of 1911 pistols. The military used "half moon" clips with 45 ACP cartridges in these revolvers because, if single-loaded, rimless 45 ACP cases must be extracted manually. The 45 Auto Rim solved this problem, and is still manufactured by Cor-Bon. Ballistics are the same as the 45 ACP: 230-grain bullet at 805 feet per second. Many 1917 revolvers are still in use and some modern revolvers have been chambered to 45 ACP and half-moon clips are available...but 45 Auto Rim cartridges and cases are simpler for casual shooting.
