Thank you

Nope. You need another set of dies for 45 ACP. Lee dies are cheap.

HTH,

Bodydoc447;
Lee dies are NOT cheap. Ahem! They are inexpensive[smilie=1:. LOL

The .45 ACP case is .473 id at the case mouth and max length of .898 from the case head to the case mouth and is a rimless case
The .45 Colt case is .480 id at the case mouth and a max length of 1.285 from case head to case mouth and is a rimmed case.
In short I agree with Bodydoc447 the dies for a .45 Colt will not load the .45 ACP.

If you are going to shoot your .45 ACP a lot, as in bullseye target shooting and the practice that bullseye makes necessary, you will be money and time ahead to start with a carbide sizer die. The time saved lubing and cleaning cases is considerable.

Thanks for the replies. I have a Ruger convertible, 45colt/45acp. I now have bunch of acp brass and was just curious as to weather or not I could use my 45colt dies to reload the acp brass. I've read somewhere (here?) that the acp dies work for the colt round and was wondering if it worked the other way around also. Don't think I'll do much reloading for the acp if I do I'll probably get the correct dies. Just thinking out loud here.

Thanks Guys

I'd save the money on dies and send the 45 ACP to me[smilie=1:

My Hornady dies will load both. They say so on the box, and I have done it myself.

Most .45 Colt seater dies come with a roll crimp. A roll crimp is necessary on .45 Colt ammo because the bullets come with a crimp groove.

Most .45 ACP seater dies come with a taper crimp. A taper crimp is necessary on .45 ACP ammo because the bullets do not have a crimp groove.

Get the carbide dies for any straight-wall handgun cases. They last much longer (much more difficult to scratch) and require little to no lubrication during sizing.

I've got one of those RBH convertibles too. If you don't have any other .45 ACP, and don't anticipate getting one, go ahead and send your ACP stuff to Cloudpeak and buy some .45 AR (Auto Rim) cases! That's what I did.:) Buy AR cases, I mean - I didn't send anything off to Cloudpeak.:roll:

I like that convertible cylinder, and the ability to try heavier boolits in the ACP, even if I haven't done it yet.[smilie=1:

I only bought 100 of the AR cases, and they have to split duty between the 25-2 and the RBH.

Myrbh has a very tight chamber in 45 acp. Much more so than the 45 Colt before it's throats were uniformed. I would expect you'll get great accuracy from it and use less powder so for plinkers I'd consider it. Gianni.

While playing around with the Glock 45 ACP, I learned that the RCBS 45 ACP T/C sizer sets case diameters at .467", and the 45 Colt T/C sizer sets them at .469". Factory loads run about .470"-.471", so I will be using the 45 Colt T/C sizer for the 45 ACP work from here on out--and I'll just neck-size 45 Colt cases about 1/3 their length.
