Guys, I have been reloading 45ACP for years on my Dillon 550. I have two 45ACP revolvers, and am wondering whether I could use the same shell holders to reload 45 auto rim cases as I use with regular 45ACP cases.
Does anybody know?
Thanks!

.45 Auto: case head diameter 0.480" and rim thickness of 0.049"
.45 Auto Rim: case head diameter of 0.516" and rim thickness of 0.090".
What do you think?

No. Totally different size.

I don't think so,the AR has a larger rim

No. I actually found several for $2 each in the "junk" bin of a local gun store.

No, I won't sell them. Kept 2 and gave one to my brother.

The RCBS shell holder number is 8 for 45AR. The Lee number is 13. The Dillon shell plate is H with #4 pins and the powder funnel is E. The powder funnel should be the same for both 45AR and 45ACP. I think your powder charges should be pretty close to same, unless you are loading high pressure max velocity loads and then they could still be but I wouldn't start that high.

OK. Thanks!
