I roll crimp .410 unfired, new hulls in 3. I dont reload them as I am not a high volume .410 shooter as you are, Stan. If I were, Id probably use a press. Roll crimps can be reloaded, but hulls dont last as long as a star-crimped load. Note in the top photo. First two on the left were roll crimped. The mouths would have to be straightened out before loading. Next is a factory load, fired. The unfired hull is last on your right. I think the reason roll crimped fired hulls are more fragile is because friction (heat) causes the plastic to bend making it more brittle than a star crimp. Unfired, primed Friocchi hulls 3, run about $15 a 100. Not bad considering the cost of factory rounds.
The last photo is my collection of .410 crimpers. Didnt start out to be a collection, but I couldnt resist buying them.
They are hard to find.
