[QUOTE="MudRunner2005, post: 1303532, member: 12995"] The powder was not the problem... It was how much of it was in the case. :D A lot of people use factory ammo to form for their AI's... I do not for this very same reason. It is too hot of a cartridge when trying to form. The brass case expands too rapidly with too much pressure and it can cause ruptures, split necks, case/head separations, etc... I use around 45 grains of RL19 with a cheap Hornady 117 Interlock for my .25-06 AI forming loads. And I use the same principal for my other Ackley Improved cartridges. I never run a full or hot load for fire-forming. But you don't want to run too light of load either. I'd use a book starter load for whatever the powder and parent case combination is. [/QUOTE]
