I've been working up a load for my .270 Win (1:10" twist Weatherby Mk V) using some 124gn Hammer Hunter projectiles. All projectiles so far have been seated 20 thousands off the lands. Below is one of my groups at 200 yards. I'm happy with the velocity (average and ES), but the group spread is around 1.43 MOA. Next, I want to test a few seating depths using this powder and projectile combo to see if I can shrink the group spread to 1 MOA max without greatly affecting the ES. If your in my shoes, what seating depths do you test next? I want to do a thorough test, but I also don't want to burn through any more components than what is necessary.
I have in mind testing these seating depths (each 4-5 shot groups):
Note: In the picture below, the far right impact is from a separate load.
