this will be my first experience loading and auto loads. I have loaded quite a few 38/357 mag and 45 colt, and 32 H & R mag. But these are all revolvers and use a roll crimp as does my 45-70 loads for a lever action. I have loaded these for Marlins and now Henry's . I also loaded for Ruger #1s and a #3 all in 45-70. And they took/recommended a good tight roll crimp.
I have had a Lee factory crimp die for those loads and the roll crimps.
