[QUOTE="lancetkenyon, post: 2670817, member: 68875"] The PRCs were designed around shooting heavier for caliber bullets. Which require faster twist barrels. What is the factory twist rate on a 300PRC rifle? 1:10" like most .300WM, with some even being 1:11"? No. 1:8" to :8.5". What is the factory twist rate on the new 7PRC barrels? 1:9" to 1:9.5" like the 7RM? No. 1:8". What is the factory twist rate on a 6.5PRC barrel? 1:9" to 1:9.25 like a .264WM or .260 Rem? No. 1:8". The twist rates are definitely geared towards the newer, heavier, higher BC bullets that have hit the market in the last 10 years. There have been three other rounds that cover the entire spectrum of hunting needs for decades. .264WM (1959), 7RM (1962), .300WM (1963). Or for more than a century in the 6.5x55 Swede (1895), 7x57 Mauser (1892), and .30-06 (1906). It is the advent of new projectiles that has spurred new cartridge designs, and faster barrel twists, which have gone hand in hand. [/QUOTE]
