If you can find someone then in your area that shoots or has any of the 338's as "rang guns" so you can try them out for a few rounds.
They are the best of the LR's currently available commercially (unless you step up to .408 Cheytac) but the recoil is considerable and not tolerable to a lot of shooters.
With the right Muzzle break, and decelerator butt pad though the .300's can be very tolerable for just about anyone.
Keep in mind that the 300wm and wsm have taken boat loads of game up to Elk Size at 1000yds for as long as they've been being produced.
Personally I'm giving serious consideration to a .338 RUM for my next build.
