45 Auto Rim

[H Richard]

Getting ready to make u a batch of 45 Auto Rim, with 245 gr Powder Coated RNFP. I'm thinking 5.0 gr 231, as I look in the Lyman book with 5.5 gr a max load. 231 is listed as "Most Accurate Powder". (Why I like the Lyman book). I will be using a Taper Crimp as I don't have a seating dye with a roll crimp. It's always worked fine with 45 ACP over the past 40+ years. Has anyone made any loads up in this general vicinity?

Lyman's so-called "accuracy" loads are simply the ones which gave the most uniform pressure and velocity in their testing. They never shot them on paper with a practical gun.

Instead seek a good performing load which YOU can shoot well. Most of the time this will NOT be the maximum load. In my S&W 325PD I load #454424 with 4 grains of Bullseye or TiteGroup which approximate 650 fps from it's 2-3/4" barrel. Your 5 grains of 231 with a 245 RNFP should perform similarly. My loads enable controlled double-taps from a very light (21 oz.) Scadium N-frame gun with manageable recoil. Ballistics approximate the .455 Webley. "A little powda, a lotta lead, shoot'em good, they be dead."

Yep, and in my many years of 1,000 yard rifle shooting, I found that the loads with the lowest velocity variations were never the most accurate loads. I load a lot of .45 AR, so I bought a special .45 ACP seating die made by RCBS the provides a roll crimp. I believe MidWayUSA has it for $36.

Redding has a .45 AR roll crimp die. If you are lucky at gun shows or EvilBay you might find an older RCBS .455 die set which will do the job.

I've reloaded lots of .45 Auto Rim with bullets in the 230-255 grain range with 5.0-5.3 grains of HP38, so you should be fine. I do roll crimp using my Lee .455 Webley die.
