Lil-Rokslider
.223->.243->.270 for me. I never killed anything with the .223 due to lack of opportunity. I was also only 8 and my dad borrowed it for me to hunt with. I've gone up slightly in the recoil department but I also went from a 6lb .243 to an 8lb .270. The difference is negligable and the stock fits a heck of a lot better. I own rifles that I'd hunt with in .243 to .375H&H on the recoil spectrum (unless the .45-70 is shooting +P+). If I got a call saying "Pack your bags, we're going hunting. The quarry and location is a surprise", I'd be grabbing my M70 EWSS in .270 and either 145gr ELD-X or 129LRX. Even in the more likely case of knowing the quarry, I'd be grabbing the .270 95% of the time.
