I'm quite sure I have enough plastic, maybe too much but I tried adjusting for that and had no luck.

I am, however, convinced that the BPI roller I'm using is probably at least a large part of the culprit. I have a 16 gauge antique roller but I broke the lever handle on it that pushes the cartridge into the crimper. I may be able to salvage the crimper and use it in the drill press. I know it makes a better crimp before it broke some years ago.

Better yet, there is a gun show this weekend, hunting seasons are largely closed, so now I have a good reason to go and a mission while I'm wading through the black guns. I need a 16 gauge hand capper too.

Thanks one and all. I'll get a good crimp on these yet.

BTW, could it be that Cheddite hulls are worse than average plastic for roll crimping? Maybe that is part of the problem. I have some old AAs that I can try too.
