[QUOTE="Wachsmann, post: 1694188, member: 10429"] I think the barrel burnout is something of bench rest shooter issues when they see there group open up from something like .2 to .5 or .6 MOA. I'm no bench rest shooter but I like to shoot a lot. I have a 6.5 that I shot 1000s of Berger 140's through and about 300 LRAB. On the last 300 LRAB's my groups opened up a lot. I went back to the Berger's and they were shooting at 1MOA. This was at 4300 to 4400 rounds. I was getting 10 reloads on my Lapua brass and I did not have a good annealing setup. It was more of a drill for spinning the brass and a torch. My rifle shot 1/2 MOA which is were I stopped with the Bergers and sorry to say I never could get the LRAB to shoot well. I haven't replace the barrel yet since I would like to go back with a similar design barrel but currently I haven't found one on the market and the wife has a few projects going on. (Single Income). Really just need to save up for it better. But mine was a 24 inch barrel and for some reason it always showed pressure sooner than most so it kept me in the 2860 to 2880 FPS range on loads but it was my favorite gun to shoot and I cut my teeth on the 1000 yard mark with this rifle. Half MOA loads with ES under 15fps generally kept me at MOA or better at 1000yards. If no wind then it was always better. So that's my take on barrel life for the 6.5X284.
