I picked up a set of RCBS 45AR dies for $2.25.

I know the cartuidge is BASED on the 45 ACP, but is it the same other than the rimmed base versus the rebated base on the ACP?

Any ideas?

Not a bad price.ACP dies can be used for the AR.Since tha case headspaces on the rim,cartridges can be roll crimped when the bullet has a crimping groove.If the bullet has no groove a light taper crimp will work.You will need a #8 shellholder/max cartridge length is 1.275"
