I know, I know... but bear with me.
As far as 20 gauge goes, nobody at out little club shoots anything but promo shells, so the pickins are slim. Looking at the inside of the Super Target & Universal hulls (yes, I cut some open), the basewad looks the same as in the AAHS. So I loaded up a couple boxes using AAHS target data. Something that I immediately noticed was that the plastic is stiffer, resulting in about 1 in 10 reloads having deformed or split crimps. I'm OK with this for a one-reload hull (they all stay closed). Am I right that I can use AAHS data for these hulls?
