I just shot my stock factory, no brake, Ruger 338 Win Mag yesterday, testing 275 gr Speer with various powders to seek the highest velocity...got almost 2700 fps with that bullet, and RL 26. Shooting from the prone turned rather brutal after 20 shots,...finished with 30 rounds and a bruised shoulder, and I'm 72 yrs old. The 416 Rigby with heavy hand loads is by far the worst recoiling rifle I own, when pushed close to 416 Wby performance.
My 338 Win Mag has killed more game animals than all my other rifles put together, ya don't seem to notice the recoil when shooting at game. I've even used it on small game before hunting season to get used to rifle, recoil, and build confidence. Most all my shots at game are 100 yds or less a fast handling 338 with 2-7x scope set on 2X is all I need 98% of the time. The 338 Win Mag kills extremely well, and instantly. So I sold my 7mm mag, which didn't kill any faster than the old 7×57 Mauser, in my experience. My other favorite is the 350 Rem Mag, 250 gr at 2625 fps 20" barrel Model 7 modified to feed 2.9" cartridges and a light low power scope, accurate and deadly at close range...big bullets make huge exit wounds, with less bloodshot meat. The lesser calibers will kill, even the 22 LR, 17 Remington, or 223 kill deer...I prefer not use them.
