If the choice is between a 9.3x62 and a .375, there isn't any.

When a fellow like Robertson says he believes the 9.3x62 actually kills cape buff quicker than a .375 H&H, I take notice. At any rate, there is enough room for argument both ways which usually means that neither will decidedly perform better than the other.

Neither of them are the absolute finest long range calibers available, but if the choice is between a 9.3x62/.375 H&H and a .270 Weatherby for buffalo, then I am confused. Sure, the .270 is going to shoot flatter, and if your main intention was mule deer, whitetail, sheep or antelope I'd say get the .270...but DON'T sell the 9.3x62 barrel.

The 50% greater powder weight and slightly heavier bullets of the .375 does seem in my guns to result in somewhat more noticeable recoil than the 9.3x62.

I do not think you will find many Canadian hunters who would take the .270 WBY over the .375 {or 9.3x62 for that matter} for bear and moose. I'm sure some will weigh in here.

Regardless of it all, if you dump that 9.3x62 barrel, I think you are making a big mistake.
