Like I stated before, in order to get a nice roll crimp, you have to load one shell and see where the final inside height is, should be a little over a 1/16" to 3/32" max over the shot card or else you will have to add more shot cards.
These are Remington Game Loads cut to 2 5/16" with the recipe I posted and roll crimped. This picture shows an old type roll crimper but the Ballistics one did the same when I got it. I don't know what they are talking about bad crimps.

The overshot cards are homemade, I was impatient to wait for the Ballistics order to come with the over shot cards and the roll crimper.
