After shooting hundreds of roll crimped shells I have the feeling that there will be no improvement in pattern using folded crimp but since I'm going to the trouble of shooting a number of loads with a number of guns throwing in a couple folded crimped shells to validate my perception seems like a good idea."
I'm attempting to open up the patterns on a tight Parker except with brass hulls and 3/4, 1, and 1 1/8 oz. loads. I'll let you know what works for me.
