Question for Trappist and dcloco. Are you using a staggered or center feed action. If the OP is looking at a SA staggered feed I agree completely. But I think shooting 80-90 the almost 3" mag of a centerfeed should work fine. I shoot 105 bergers and 107 smk's in a centerfeed 243 and have ample mag room. I do agree that the throating makes all the differance. I have a 700 in a 6mm rem also and fight the short box in it. Its a great cartridge, good luck. Eric
