bullets for 45 colt and 45 acp

Am now loading my own 45 colt, and been shooting 200 grain harden lead or jackets bullets. (The jacketed group much better.) Anyway, was bullet shoping and ran across some 45 cal bullets designated for ACP. Didn't think about it at the time, so I didn't read the specs . . . what's the difference? (And no, of course I didn't buy them for my 45 colt.)

I use .45 acp bullets almost exclusively in .45 Colt carbine.

Some .45 Colt revo's might prefer .454" lead, most auto bullets will be .452".
Otherwise it's all about fit in your particular gun and matching the hardness to your pressure levels.

The .45 acp will lack the crimp groove of the .45 colt bullets.

.45acp is .451", 45 colt is .452" close enough to be interchangeable, (it could also be .454", depending on who you ask, I have also heard to use .454" if using lead and .452" if using jacketed). But any modern gun should be .452", from what I hear.

Lead bullets for both should be .452. Jacketed bullets for both should by .451.
45 ACP lead bullets may or may not have a crimp groove.
You would probably get better results in both by using a softer lead bullet, rather than a harder.

45 ACP lead bullets are fine for 45 Colt light plinking loads. .452.

.45 acp bullets can be crimped over the shoulder on SWC's or on the ogive with LRNs. The deeper seating helps reduce wasted space in the case. The data will usually give a specific OAL for pistol bullets.

I load lead 452 45acp bullets for my plinking rounds, my 45LC does not know the difference.

The Lee 230 grain tumble-lube truncated cone bullet is supposed to be a full-weight .45 ACP bullet, but it also works great in .45 Colt. Just crimp into the top groove.
