Re: Caliber choosen.....which bullet?
I'm most probably in the minority here as I notice that most are leaning towards the 225s. From my own research and talking to the folks that know and from working up hunting loads I have some experience. Plus as it looks like you are going to build or have the rifle built I presume that you are considering throat considerations for the bullet of choice (which is good) I'd say this:
I'd recommend a 250gr bullet over any 225gr bullet. Why, if you're shooting a 338 you may as well shoot a 338 and not a 30 cal. (That's just me, though)
Also if it'll seat a 250gr bullet and the chamber is properly cut, the 225 will shoot just as well.
I have a Holland brake on the old girl and recoil is not a problem on the shoulder. It was on the scope mounts though. [img]/ubbthreads/images/graemlins/frown.gif[/img]
Of bullets of that weight, if I were designing the rifle from the ground up I'd go with the Wildcat 252 gr RBBT and have the the throat cut so that you have as much room for powder as practicable.
Why: In my rifle factory REM 700, they shot 1/4 MOA. Their jacket is great and seeing as how the griz will be delisted in a year or so, I'll be able to defend the elk carcass and let the griz have the gut pile. [img]/ubbthreads/images/graemlins/grin.gif[/img]
Also, I'd recommend if you are going to go with a gunsmith, I'd recommend one on this board as they have the long range hunting/shooting experience and have great track records and reputations.
Sounds like a great project. Keep us posted.
