Does it make any difference to the load itself which crimp you use? In my VERY limited understanding, it seems to be easier to keep things snug inside with a roll crimp. Is that wrong? I was thinking of ordering a roll crimper and spin doctor for the drill press, along with a bag of over shot cards or maybe buying a punch and making my own.
How would one approach a roll crimp with say, a Lee slug or a 9 pellet buck shot load?
...or is it a waste of time.
