Hi, picked up a model 10 sba in 308 recently, but while trying to sight it in ran across a box of hot Federal 180gr that was blowing some of the primers out. Contacted Federal and they disavowed all responsibility for it because they were over a year old, never the less had to take it apart to get the primers out of the action. Once I put it back together shots weren't anywhere close to the previous settings and wouldn't group at all.

Read up on torque settings and have tried some different ones, most 3 round groups now are in the 1-2 inch range at 100 yds, a couple under 1 inch. For a heavy barrel Savage this doesn't seem right, have an old Stevens 200 in 223 with a light barrel that will put 4 shots in a half inch and 5 in 3/4. Have tried a range of ammo with it from standard hunting loads from Remington, Federal and Winchester to some nicer stuff from ADI and handloads. I'm expecting it should be capable of shooting a 1 hole group, is that reasonable?

Thanks for the help!
