500 grains is right and the above statement is pure fantasy. Yes, the bore rifles were, IN THEIR TIME, probably the best choice for elephant, and were thus touted as such by many hunters. However, that was a time when there was nothing available that was really ideal for such game.

The advent of Cordite and nickel-jacketed bullets permitted a combination of velocity, sectional density, and bullet integrity that had never been possible before. This gave the Nitro Expresses a markedly superior standard of performance, especially in terms of reliable penetration, and these were the first rifles that were truly ideal for thick-skinned dangerous game. Had it not been so badly outclassed in it's only really useful application, the bore rifle would certainly have lingered for quite a while. The reality is that the Nitro Express relegated it to extinction in a phenominally brief time span.

Bore rifles are wonderful pieces of history and a trip down Nostalgia Lane to shoot and hunt with, but lets not lose touch with reality.
