Re: For the 7WSM shooters...barrel life?
I've got 1,400+ documented F-Class competition rounds (as in 25 shots in about 18 minutes, wait an hour or so and do it again). SO far she is shooting just fine. No visible signs of opening up.
I've heard that GEorge from GA Precision thinks he'll get about 3K from his - he shoots moly if memory serves.
