I'm shooting a factory 22" Ruger in the RCM, it replaced both the Federal and Winchester 338s I had.
Wonderful cartridge and has become my favorite rife/cartridge combination.
225 ABs at 2,750, with a .550 bc easily takes me to 750 yds on larger game.
The 250 Partion leaves the barrel at 2,600 with RL16
