Thread: Fire forming AI brass

Hey, this is a process I have not done before and I was thinking of doing this without a projectile. The general method I can find on the net is to use about 10g pistol powder (Unique, AP70N) Cream of Wheat to the neck junction and then plug with polyester filler. Easy if you know what that shit is! I guess Cream of wheat could be substitute with semolina? and the polyester filler is just the stuffing out of a pillow? Any ideas would be appreciated or do I just fire form with loaded ammo. It just makes sense to me to save the barrel from another 100 rounds as well as the reduced cost of more pills etc.
