416Rigby: As to failures of the 375 on dangerous game see page 44 of the April 2000 issue of Handloader No.204 where Ross Seyfried mentions a solid from a 375 that broke up on the shoulder knuckle of a buff after 2" of penetration. As an aside in a story on 416's. [BTW that buff was stopped with a 400 grain swift A-frame from a 416 Taylor]
And Ross doesn't bash the 375, he recomends the 375 or 416 for most people as heaviest rifle they need for hunting Africa.
I suspect that the reason we hear about failures from the 375 and the 458 Win is because they are the rounds used most often. So they do have a greater total number of failures even if they have a higher % sucess rate.
That and for the 375 I think you need very tough solids because it is a high velocity cartridge for solid use. The standard velocity for most NE rounds is ~2100 right? With the 416 Rigby at ~2370. [Note also that Bell's 7x57 with the 173 grainers would have been doing about same velocity as the 416 IIRC]
