[QUOTE="Charles A, post: 24902, member: 231"] Went to the range today to try some new loads. Rifle was M70 300winmag, Leupold 6-18/40 target, off a harris bipod, shot nearly free recoil. Loads were all Rem cases and CCI 250 magnum primers. Bullets were 178gr Hornady A-max(thanks S1), RL22 powder, oal. 3.555 When I left there was very little wind. At the range wind was 5-8mph from 4:30-6:00 o'clock. All groups were shot at 100yds. Three targets left to right and another three below. 75gr shot at first target. 75.5gr shot at second target. 76gr shot at third. Then 75gr at first target on bottem, 75.5 at next, etc., etc.. Untill I had shot six three shot groups. This, I believe gives a more representitve group size, as all rounds have the same amount of fouling. Anyways the average group size was .71moa. With the sweet spot at 76gr, average was .48moa, largest, .555moa. Smallest measured .421moa.
