My fellow competitors shooting 7 saum/imp cartridges with similar projectiles and velocities are getting 1200-1400 match rounds before retiring the barrel. I had 1800 rds on my first 7 Sherman Short barrel when I placed a very close 2nd in last year’s Texas state 600yd f-class championship. I pulled that barrel just because I had another ready and it had to be on the edge. Funny thing was I said that at 1400rds and it kept on shooting. I think the long neck, its 40deg shoulder and efficiency with slow cool powders is a big advantage that translates into significantly longer barrel life. For a large game hunting rifle that sees much less rounds in its life that may not be significant.
