This is a military ammo question..

[skeet]

Maybe a reloading question too. Anyway..this is the scenario.

A friend called me last evening with a question about reloading 308. Military 7.62 x 51 to be precise.. He had gotten a couple thousand rounds from a friend..They proceeded to process the brass and ultimately loaded 650 rounds. One fellow has an M1A Springfield Armory to be exact. Well they tried the function by cycling in an old Ishapore 308 Rifle....every thing worked just fine so they finally got to try some through the M1A..and it just won't fit in the chamber.. Measured the case and at the base above the web the darn things measure .488..way more than they are supposed to. These were sized in a normal 308 Win sizing die..and still measured that..I suspect these were shot in one of the new iterations of the M-60..machine gun if ya will. Is there any way to re-size the brass to fit a standard chamber..or do y'all think the brass is stretched beyond hope? We tried to resize the brass in a 30-06 small base die and a 243 die..nothing changed..still came out .487-.488. I think they are gonna be pullin a lot of bullets. Any answers that may help?? Unfortunately..I even have a hundred or so of this brass. Should we just crush it and sell it for scrap??
