I took it apart and double checked everything because I had a problem with my Savage 111 because the action screws had been tightened wrong (my fault). After removing and reinstalling the screws properly, the rifle was back to normal. In this case, the gun hadn't been apart (I took the stock off the Savage to adjust the Accu-Trigger), so I didn't suspect that that was the problem, but wanted to check for stock swelling or cracking and such. I just loaded another batch of ammo, seating the bullets out so they are only one caliber into the neck (and still have PLENTY of freebore left), and tried also worked up to 2 grains higher. Bore was cleaned with several rounds of Hoppe's #9 Nitro solvent and Shooter's Choice copper solvent, and then for good measure, I gave lapped it with JB Bore Paste on a tight patch. The bore not looks very shiney and smooth.

I suspect that the Barnes TSX's fouled the bore up, but because they have the grooves they still shot great. When I switched to the cup and core Accubonds and BT's, the copper problem reared it's head. If the wife doesn't have a 10 page honey-do list for me, I'm going to try to get back to the range tomorrow and see if the problem had been corrected. I've got my fingers crossed...
