[QUOTE="MudRunner2005, post: 1491630, member: 12995"] I don't use the COW method... I use the live-fire method, where I load up a light charge (usually about 5 grains less than a book starting load) of rifle powder (usually RL-19 or RL-22) and a cheap Hornady Interlock bullet and a cheap CCI primer. I seat the bullets touching the lands (slight bolt pressure when I close the bolt) so I know its properly seated against the bolt face and the lands, and will properly form to my chamber. Then I shoot 5, let it cool. Shoot 5, let it cool. I usually do about 50 per session, and with properly formed AI brass (from good quality brass), they should last a good while if you don't load them super hot. Also, you're using .25-06 brass. When forming for an AI chamber, when the brass gets fire-formed, it scavenges brass from somewhere as the brass flows to fill the chamber walls while forming. This brass will mostly come from the neck length. Example.. I tried forming .25-06 AI brass from .25-06 Rem brass, and the necks came up 0.020" too short. So, i started forming using .270 Win brass, that I FL sized in a .270 Win die, then necked-down to .257 in my FL .25-06 AI die. Then I trim the necks 0.020" too long, and when they fire-form in my chamber, they come out at a proper 2.494" length. [/QUOTE]
