My 12 year old Cooper LRH hunting rifle in 6.5x284 has a Wilson barrel. As mentioned, Wilson Barrels owns Cooper. With 1000 rounds it has no visible barrel wear/fire cracking, with the same BTO, and has consistently held .25 MOA accuracy with single digit SD's over all these years. I consider it one of the best barrels I've owned. The kicker is,,,If or when the barrel does finally give out, Coopers warranty claims replacement for $125! JLK Group:2010, Berger Group:2021
