Gave a buddy a box full of old .22-250 brass. buddy came back with 200 cast projectiles. lead gas checked. mike out at .311 to .312. could these be fired in my .30-06.? my cast loads at present are 180 gr. with 47 gr. h4350. good for 2-2 1/2 " at 100yds. would like to make use of these if possible. the gas checks mike out at.309-.310" and that is my concern. thanks for any input GLENN
