First off, I know about the barrel life, I will only be shooting about 100rnds a year if that, because of work, and it will be used for groundhogs at very long range, so the barrel will last me years, and I can always buy another barrel. I have a place I shoot up to 1500yds easy. I dont care about cost of brass, powder etc... The only other thing I can think of is a 264 win mag I might want to build. I have a tuned up Mag L/A and a 6.5 Rock barrel just waiting. let me know. You guys are Super Duper Smart here so let me know, I value your advice
