Re: 7 rum
From my research a couple of years ago, I was really sold on the 7STW. It will slightly out run the RUM and with a 162 A-max or 180 Berger you are going to kill anything within 1500yrds with that round. Barrel life is a tough one to assume. It depends on bullets, powders, and velocity. The slower the powder the better the barrel life. The lighter the bullet, higher velocity, more throat erosion due to faster burning powders, equals shorter barrel life. So it is a matter of what you want to do. You don't have to push it to its max either if you can find a lower power load that works. Making sure you clean regularly but not over cleaning will determine your barrel life. If you run 180's with slow powders, you can probably expect 800 to 1000, but that might be pushing it.
