I had dropped the charge several months ago by .2 tenths to keep it in tune.. withe the aggressive cleaning I gave it i needed to add that back.. the change helped.. got it back under half moa.. (top left two groups)Wanted better so i did a seating test from .015 off to the .040 off in my first two groups in .005 increments.. looks like .025 off is where it needs to be.. thats around 1/4 moa.. with throat growth in the rifle that puts me back to almost my original load and jump.. target is at 250 yards
