.45ACP Bullet Setback

[7075-T7]

I know this has been covered on the forum before, but I only saw info about the .40S&W. Is it something to worry about on the lower pressure .45? I have a winchester silvertip I've cycled a few times, and it looks shorter than the others (I've not caliper'd it yet).

If it's just a "hair' shorter I'd go on and shoot it.....IF it's noticeably shorter, as in the ogive is almost gone (measure it), then use your own better judgement.
Remember, whether reload or factory, changing the cartridge over all length via bullet seating depth, effects the space in the case and
thus the pressure.

I've yet to actually see any bullet setback in a .45 ACP cartridge.

Setback is always a problem. In lower pressure cartridges it isn't big of a problem as in the higher pressure cartridges. I'm with Andy on this one if it looks too short don't shoot it. TAM .45 ACP will setback any straight wall uncrimped round is susceptible to setback.

It happens to me on my 1911 quite a bit. If I cycle a round more than 3 times, it is noticeably set back.

I believe you, I've just never personally seen any noticeable setback in a .45 ACP cartridge. OTH, I don't tend to recycle rounds that often.
