I purchased two of these back in 2023 when they were only offered in 6mm. I got a screaming deal at the WAR two day match and figured why not. Bore scoped both barrels, looked great. Chambered both of them in 6 Dasher. Ran the first barrel at 2840 with Berger 105’s. Barrel shot great for about 1500 rounds when it started holding on to excessive amount of copper. By 1700 rounds it struggled to hold a water line 700-1000yds. By 1800 rounds I pulled the barrel. The other barrel was spun on this year but I haven’t shot the rifle enough for longevity claims.
