I am working on the 'next' rifle project. The base of the case will be .600 plus so I'm looking into .750 bolt face actions. Normally I prefer Why Mark V but the .720 face does not make me comfortable when exceeding 338LM,460Wby base dimensions. There is a 'Big' Hall available near me, Stiller Predator Extreme/TAC 338 or Nesika with a delivery wait. I'm not going as big as a CheyTac. For that I would go with a Stiller 408. Suggestions or comments please.
