So....had a chance to test A Tips and 109's @600yds. Nice calm conditions. I shot 2, 10 shot groups with my go to 115 VLD load, both those groups were under 1 moa so I know the rifle is shooting OK.
I had 5 A Tip rounds left over from the other day so I sent them down range, that 5 shot group was damm near 2 moa!.....no wonder I was all over the target the other day, besides having the swirling winds. When I tested this same load @ 200yds, it was shooting 3/8 moa. Not sure what I am doing wrong with these things.
I then shot 8, 5 shot groups with the 109's, 2 groups with .010 jump and 2 with .020 and charge weights of 43.8 to 44.2, all shot well but the 43.8 shot just over 1/2 moa. velocity at the target avg. 2029 and an 11.9 SD.
I need to do some more work with loads, but starting to lean towards the 109's.
