I have to agree here, I had a 300 RUM for 2 years because thats all the barrel lasted me. I shot it around 1000-1200 rounds before accuracy was really noticably falling off past 500 yards. Inside 500, it was still deadly. However, for as much as I like to practice with my rifles, the 300 RUM is just a powder burning, barrel burning son of a gun. I downsized to a 7mm RM and am just as happy. Of course it doesn't have the raw power, but you dont always need that much power...I still personally like the good old 300 Win Mag. Cant go wrong with that one. It will give at least double the barrel life of a 300 RUM, w/out sacrificing a whole lot in the ballistics department.
