The heyday of the 222 Remington was a little before my time. I read that it was THE bench rest cartridge, dominating the competition for years. What barrel twist were those winning guns using? 14? What bullet was the best? I'm assuming something like a 53 grain SMK. I plan to re-barrel an old rifle. I'm seriously leaning towards a 14 twist, which it has now, but sometimes wonder if there would be any down side to a 12. I'd like to shoot 40 to 50 grain bullets, maybe up to 55 grains.
