I thought Jack Lott was using a 375 H&H when he got tossed?
A 460 WBY and a 416 WBY seemed to kick the worst to me.
I have fired over 300 rounds in a day from Barrett .50 cal rifles. The bolt rifles thump pretty good, but the semi-auto is not that bad.
I have found that recoil velocity hurts me more than total ftlbs of recoil.
For example 20 rounds of unbraked 300 win mag bother me more than 20 rounds of 450/400.
20 rounds of 375 H&H from a light rifle bother me more than 20 rounds from my 450 No2.
I would really like to shoot a 577 and a 600 double rifle.

Dugaboy has a very valid point, that after my Safari in Zimbabwe I proved to myself. A .458 cal. 480/500 grain bullet at 2100 to 2150 fps. is a great killer/stopper with very managable recoil.

I still want a 577 or a 600 for my next elephant hunt.

I KNOW I do not need it, my 450 No2 was SUPERB.... I have just read to many old elephant hunting books.
