Sounds like your good to go. Me I would keep tinkering. First I would get a Lee Collet Die and second I would hone or have RCBS hone the FL sizer to your chamber. I might even take the seater die to the gun smith and have him re-ream it with the chamber reamer he used on your rifle. You are already getting good accuracy so debatable how much more these steps would give you, but they are likely to provide some improvement, possibly a lot.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
