As much as I hate the recoil of the .338 I would much prefer it over the .300 Mag. I do prefer the .375H&H above all others for shooting heavy bullets. But then I don't like being beaten by recoil.

Thus saith thr lord; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeh from the lord. Jeremiah 17:5 KJV
