The 264 Win mag is a real screamer. I like the 6.5 caliber and have had the 260 and 6.5 Swedish Mauser. If you reload you can down load it until you need the speed. This will make your barrel last longer. The 264 earned its reputation for burniong up barrels and full power loads have done it in as little as 1000 rounds. I like it mush better than the 7MM Rem Mag. It never lived up to Winchesters plans as the 264 caliber does not burn up the sales charts. I am waiting for the 264 WSM or WSSM. I hope they do it.
