My 1 in 10" twist 300 RUM won't shoot the 200 gr AB under moa at 100 yds and it doesn't get better at longer range. It will shoot the 180 gr Sierra SBT under 0.4" at 100 yds but I would like to shoot a higher BC bullet. Just wondering if others who have not had good luck with the 200 gr AB have had good luck with the 190 and/or 210 gr VLD's?
