I've always just substituted a shorter wad. I find a recipe say using a Claybuster wad with a 1oz load [ CB-1100 ] and instead use a CB- 1138, meant for a 1 3/8oz load. It will have a shorter cushion length which means a shorter stack height giving you the necessary room to fold crimp. If you're going to roll crimp then just cut off a 1/4" of shell, you'll have enough room. I've also always just used the 2 3/4' data for my 2 1/2" shells. Good luck - Paul
