[QUOTE="MagnumManiac, post: 2054278, member: 10755"] If the AI chamber is cut correctly with negative headspace of .003”-.005”, then you should be good to go using a NORMAL load to form brass. If 3031 is all you have, use a middle load, not a start load. If not, then a forming load using a fast pistol powder, COW (Cream Of Wheat) and a snug piece of of TP is in order with a false shoulder to keep the case head against the bolt. I use Clays to form all of my improved cases, including my 375 Weatherby and 338-416 Rigby Improved. My 22-250AI only needs 10gr to form a case, the next full powder load gets all corners nice and sharp. Cheers. [/QUOTE]
