So I decided to try some AA2520 for 30-06 in my M1
I settled on 46.0 grains, Im using CCI No 34 primer. Bullet is Hornady 155gr HPBT
My seating Depths were
3.330
3.320
3.310
3.300
3.290
In attached image, best accuracy came at 3.320 and 3.310 I shot 10 shot groups instead of 5
would my next step be to narrow the seating depths in .003 increments between 3.320 and 3.310
the group at at 3.320 I had 5 shots almost in same hole. The lighting wasnt great so my tiny black dot at 50yds was getting difficult too see
