According to my manuals, 45 ACP brass maximum length is .898". The brass spec says to trim to .893". I have a few cases, which after resizing, measure .888" to .890". Is the .893" trim length considered the case minimum size and any shorter should be discarded? |

Okay, this perhaps might be a bit strange to say: it depends on your gun.
My S&W 1911 will experience misfires with that short case lenght. The round will enter the chamber to far/deep, preventing the firing pin to hit the primer properly. So if it's just a couple cases that are a bit on the short side, just discard them to be sure/safe. If you have a lot of them that have the same lenght you might try if they function properly.
I had a S&W 4506 that had no trouble with shorter cases. But that gun has a different firing pin assembly than my 1911 and was less picky.
The rounds them self might look like they fit correctly but misfires might occur with to short cases. If you also seat the primers pretty deep, than this will have a ripple effect. At least these are my experiences with that kind of .45ACP case length.

Thanks PJ, sounds like a reasonable approach. It's only about 5 in a hundred that are below the trim length so I'll toss them...
