The .45 A.C.P.
Nation Year Max. press.
U.S.A. 1905 22000psi
My favorite cartidge for handguns. I have a special page for this round, so I will not repeat what I have already writen. This was an attempt to resurect the performance of the old .45 Long Colt for use in a new type of pistol (the semi auto). The military had been growing nostalgic and misty eyed over the old round and the legendary stopping power it had produced. The history of this mind set and of the war with the Moros which spawned it is recorded in many other places, and I see no reson to ramble on about it here. Suffice it to say that the new issue .38 caliber pistols were found lacking, while the old .45 and it's contribution to the winning of the west were legend (and still are).The new smokeless powders permitted the same cartridge to, in essence, be loaded into a much shorter case. A comparison of the ballistics of the two rounds will show them to be almost identical.
