Re: Perplexed with my 798
Sounds like you have all the correct ingrediants for good accuracy in your rifle.
You don`t mention what powder (s) you`ve tried? Have you worked with seating depths? Is in fact your barrel freefloted? Does the action flex when you draw down the guard screws? (Bad things happen with Mausers should this be the case) and while on the subject of screws, have you checked them for tightness?
IMHO, the 06, with the bullets you listed, and 4350 powder should keep you satisfied.
