JACKETED BULLETS

* This is a good load, very accurate, but the bullet is designed for the .45 Colt. I don’t believe you will see any expansion on game at this velocity. But just the same it is among the most accurate .451-inch bullets, not only in the .45 AR but in my .45 ACP and .460 Rowland pistols as well. It certainly has enough penetration for most purposes.

LEAD BULLETS

The bulk of .45 Auto Rim ammunition was fired in the 1917 revolvers. Elmer Keith designed a semi-wadcutter bullet just for the short chambers of this revolver (238-grain Lyman #452423 – now sadly out of production but occasionally available on the used market). Short chambers are the one real failing of the .45 AR. The 1917s and even some modern 625s will not accept the longer 250-grain bullets, so the 200- to 240-grain SWCs are used. The 1955 Targets usually accept heavier bullets. Also, some of the modern runs of 625s will not function properly without moon clips when firing the .45 ACP. They simply will not headspace correctly unless .45 AR or clipped .45 ACP cartridges are used.
