Over the last 43 that I have been guiding bear hunters in Alaska I have always been building and trying different actions and calibers and since I wrote that piece I have become fond of the 9.3x62 and the 416 Ruger. I cant say I have noticed any difference in killing power between the 9.3 and the 375 (Ruger or H&H) and the 416 Ruger falls directly between the 375 & the 458. But the more I try and use other big bores, the more impressed I still am with the standard 458 when dealing with wounded bears
