[QUOTE="bdyal1972, post: 1966064, member: 50039"] I have seen Mark 248 and Mark 248 mod 1 ammo shot out of rechambered m24s with oversized chambers to guarantee easy extraction. In the early 90s I saw 220 match kings chrono ALMOST 3100fps!!! Out of a 26" barrel.... I also saw a 231 grain high bc bullet over 3000fps... It was MUCH MUCH MORE STABLE AND ACCURATE AT 1500 YARDS. THIS AMMO WAS MADE AT The REAR of these chambers were MANY THOUSANDTHS LARGER THAN CASE DESIGN IN A CONICAL FASHION... THESE FIRED CASES ALMOST FELL OUT OF THE CHAMBER!!! BTW 1/2 TO 3/4 MOA @ 1000 YDS @ -10DEG, 50DEG AND 100DEG FOR 5 ROUND GROUPS WAS THE NORM, 3/4 MOA FOR 10 ROUND GROUPS WAS MAX FOR A NEW RIFLE TO DEPLOY ON A NEW BARREL... I suspect maybe you have brass from these uses maybe? [/QUOTE]
