Can I squeeze out more without spending?
I've got an r700 in 7mm rem mag w/ nikon 6-18. I worked the old style trigger to a very crisp 3.5 lbs, I fitted and floated a Boyds LRS thumbhole, (very nice IMO) then bedded the action. With federal premiums it groups about 1"@100 but I'm greedy I want more than that. So after some extensive testing with Sierras, Burgers, and Barnes' the best I can come up with is .55"@100.
Is there anything else I can do to squeeze out better accuracy without going to the smith? -or have I done everything I can before truing the action and upgrading the barrel?
