jake, step by step how to make brass for a 6.5/06 AI
take a 25/06 brass
prime, don't even resize
put in a max 6.5/06 powder charge
seat any boattail 6.5 bullet
shoot it, out pops a fully formed 6.5/06 AI brass, though your first loads won't be full power in the AI, the 6.5/06 is no slouch, will pick up another 100-125 fps after you shoot them once. it is the easiest wildcat there is to get brass.
some AI shooters swear you can load them to max right off the bat cause all your doing is changing the shoulder angle.
