My advise would be to get a real shotgun shell loading press. A Mec 600 Jr. would be good as anything.
You can get one for $85 off Ebay. One on there right now in 20ga.
I don't know how all this roll crimp and shot card business ever got started with the turkey hunter crowd... Every time I see a post about this stuff and someone showing off their "Roll Crimp" I want to ask them WTH they are doing. They did away with that 40 years ago and told everyone then that the cards blew holes in the patterns. Maybe they did or maybe they didn't. Doesn't matter. Why you going to fiddle with all that stuff in the first place. Doesn't make sense.
Do it right. Get a press. You'll run circles around someone using a drill and a bunch of hand dies.
