Precision Reloading sells one with two balls for the same price BPs sells their one ball. Sometimes they go on sale - think mine was $20 last time. One of the guys at the club gave me a Supersizer - needed a spring. It makes a fine vice to hold the shells when roll crimping.

Just what I was thinking. I'd rather a collet type, than a vise type.

That Precision Reloading roll crimper has 4 bumps in it, not 2. Was just messing around yesterday and noticed it. I must doing something wrong - I always get one bad spot in the roll crimp - it doesn't roll over good. What way should it rotate ? The bumps have a tappered lead in , then it drops off 90 degrees. Should the sharp edge hit the shell first, or the tappered lead in ?

Paul - I'm rather certain that the roll crimpers are designed to go clockwise. That bad spot may be from you starting the crimper from a dead stop with the crimper against the mouth of the case. You might also look at the condition of the mouth if it's paper hulls you are talking about, here. Perhaps a little heat on the mouth, like holding it against a hot iron and then touching it into a saucer with a melted candle that has hardened into a cookie. The hot hull mouth will absorb just a bit of wax and maybe solve the problem.

I start with the crimper moving but you might be on to something with the wax. I have an old plug that gets hot and I rotate the shell around it with a candle applied to it. I had stopped doing that - have to try it again. Thanks.

These are the crimps I'm getting now. I gave up on the drill press roll crimper, and went old school. The crimper is an old BGI, and is convertible from rounded crimps to square crimps. It takes no more than 5 turns on the crank. The rear two shells are 2 3/4 spent RSTs (Cheddite) trimmed down, and front two are new paper Chedites. I don't heat or treat the lip, and I don't have to use a vise or collet to hold them. It takes about 3-4 minutes to roll 25 shells. I couldn't be more pleased with the results.

not surprising - the tools used when roll crimps were in every day use can still do the job

mighty nice crimps.. charrlie

Edger those are really good looking crimps. I use a drill press and one of the crimping tools and I dont think I can roll crimp as many shells in that lenth of time. I did discover that technique is everything.

Edgar, that's a shell every six seconds - man, that's moving. I'd screw something up at that rate. They are very nice looking shells.
