My LEE AUTO-PRIME will not fit a 375RUM case. Which priming tools would you recommend?

Had the same problem with the autoprime and my 450/110 cases today. I fixed the problem by opening up the top of the autoprime with a round file. Just open up the entire circumference of the top with the file until the case is properly centered over the priming plunger. Take it slow and be sure not to remove too much metal in one place.

Good luck,

I opened my lee auto-primer up also. It didn't take much to do it (I didn't have a file so I used a pair of tin snips a little off each side).

Dan375RUM,

I use the RCBS, works fine with mine.
