Re: 6.5-06 AI fire form loads???
Pick a cheap long for caliber bullet, seat it so that it jams into the lands when you close the bolt with a stiff load (for the parent cartridge i.e. 6.5-06 non imp). This will help from stretching the web of your cases, as there is no room to grow in the rear portion of the case, only room to grow in the front. I've fireformed hundreds of AI rounds this way, usually results in good enough accuracy to target practice or shoot prairie dogs.
