Keep in mind, Ryan, that bullet technology has evolved dramatically since Larry Kelly passed and since Ross stopped hunting with a handgun for editorial. Ross even used a jacketed solid (Trophy Bonded Sledge Hammer if memory serves) that he cut down and tweaked to feed his .475 with knowing there was a better solution for big dangerous game than hard cast bullets that can be compromised if pushed to fast. However, he had problems with bullets pulling but sometimes he shot first with that solid. So bullet technology played a role in bigger and bigger calibers being developed. Look at the various Nitro Express cartridges. When they were in their infancy, jacketed bullets were crap (in a word), and the obvious solution was to throw bigger and bigger bullets at game to make up for the bullet shortcomings. Keep in mind that the rifle DG hunters are just recently beginning to embrace the concept of the flat-nosed solid when handgun guys have been using them for decades. So, things don't always move so fast and bullet technology over that last decade, decade and a half has been remarkable.

I would rather use a 10mm with a proper solid that I know won't distort and that will penetrate straight and deep than a bigger hammer like a .500 Smith & Wesson with a lousy round-nosed solid. Guess which one will be more effective on a big bovine.
