Simply put. while it may be "out of spec", if it works, it's not too short.
It might not be the most accurate possible, but is that a practical consideration for you? How accurate is your gun (match gun?? service grade??) and how accurate are YOU, with it??
I've got my Dad's Govt Model, which was set up for target shooting in the late 60s, with 200gr swc's (and no sorting brass for length) it will put 5 shots in one hole at 25yds. From a bench, in MY hands.
Had a 1943 Reminton Rand GI gun, which would shoot about a 6in group at 25yds, no matter what ammo was used. Good enough for COM hits at close range, but not much else.
SO, I don't worry about .45acp brass length, unless, it doesn't feed, fire, and eject. Then, I change something....
