Hello, I am having trouble getting a roll crimp on Fiocchi shells, blue in color.. I cant even begin to get a usable crimp using a drill type crimper and overshot wads. I fill the shell with shot and then the card then I put the tool from BPI in my drill. I get some preetty bad looking crimps. What can I be doing wrong? Thanks,Tom

Were the shells originally star crimped? You're not- going to be able to roll crimp any shell UNLESS it new, never been fired. If it was originally a roll crimped shell, you should have no trouble.
A roll crimper needs to run at high RPM and the down pressure has to be heavy. Then it will work well. You also MUST be totally square with the hull body. It's best done in a drill press, where you can run it fast, AND get it square.

HKSP, what snuffy said about speed & pressure but there is hope with once fired hulls, one of these http://www.ballisticproducts.com/prodinfo.asp?number=SPINDOC will go a long way to iron out the kinks in a hull mouth, I've been using one I got a fitter at work to spin up from this pic & after that I get quite acceptable roll crimps, it pays to trim a tiny bit off the case mouth to tidy it up which seems to help, I'm using a Lyman roll crimp tool in 12 gauge. The info with the Lyman tool does say that after roll crimping once you won't get a second go at that hull. Hell, hulls are cheap, pick ups at the gun club.

Hello, I am using new shells. I am also using a cordless drill. The battery might be weak and my RPMs are too slow. When I get time I will try another drill. I bet the lack of heat due to not enough friction is my problem. The shell look nothing like being crimped and more like being twisted on with a pair of pliers. thanks,Tom

The info with the Lyman tool recommended 600-800 rpm, not sure what I had the drill set to, no rev counter, but I ran it moderately fast & that got the plastic hot & soft quite quickly, it also took a reasonable amount of pressure applied steadily rather than all at once to get the crimp to roll over.
