I ordered a die set for .45 Auto. The set I received was for a .45 Auto Rim. I was told there was no such thing as a die set for rim fire. Did I get the wrong thing?????

ask the maker

The Auto Rim is a rimmed case for use in an ACP revolver; moon clips are not required. It would use a different shellholder. The only difference I see would be in the seating die if the Auto Rim gets a rolled crimp.

Did you order a Redding Pro-Series die set? If so, you were sent an 89190; the set for ACP is 89189.

Case dimensions are identical other then being rimmed and rimless. Body tapper diameter etc... All the same.
Personally I'd send them back and get ACP dies.

I use RCBS 45 Auto dies to load the ACP case and the Auto Rim case, just need a different shell holder (Duh!!).

As usual, YMMV!!

Yes, mine is a Lee and the only difference is he shellholder. Thanks

Will the Lee Factory Crimp Die allow the cartridge to index on the case neck? The Factory crimp die is 90864; the taper crimp die is 90785.

Factory crip die from lee is actually easier to use then the taper crimp. and yes it will head space properly as long as it is properly adjusted but it is very difficult to screw up.

With my RCBS crimp die, I can adjust to do a roll crimp (if I should want to, which I don't) for the Auto Rim cases. I don't shoot hot loads in my Auto Rim revolvers---that's what magnums are for!!

I use just enough crimp to turn the case mouths very slightly into the bullets---actually just enough so that the cases are no longer belled; works for both auto and auto rim cases.

When using lead semi-wadcutter bullets for the .45 Auto with less than full loads, I seat the bullets so that the shoulder of the bullet is slightly against the beginning of the rifling ( about 1/16 inch longer than case mouth). Works OK but could cause problems with accumulation of lead bits at the front of the chamber if lots of rounds were fired without cleaning. With this set-up, the round is actually headspacing on the bullet shoulder; the actual length will vary depending on your barrel. I can't EVER remember finding a .45 Auto case that was as long as it should be!!

When I load jacketed bullets for the .45 Auto, I adjust the crimp die to just straighten the case mouth. Some jacketed bullets have crimping grooves but I don't actually crimp the cases----only enough to make sure they aren't belled.

One other tidbit, long ago I loaded jacketed hollowpoints for the 45 Auto and to get the bullets to stay in place without crimping (for the ride up the feed ramp) I would run each case about 1/2 to 2/3 of the case length into a 30-06 size die. That reduced the case dia. just enough to hold the bullets very tight in the .45 case. To get this to work, you might have to try a .308 or .270 or some other die to come up with a combination that will work for your brass. All 45 brass ain't created equal!!
I don't do it any longer----too much trouble with the factory hollow points that are available now.

Cheers,
Jim
