[QUOTE="tacomHQ, post: 1720571, member: 67159"] Our structured barrel is specifically designed for long extended shot strings. We agree with the earlier post of 13% increase in surface area (drawings and calcs available) and minimum weight reduction. For us surface area is well north of 300% greater and 50+% stiffer weight for weight. Our testing is based on 50 rounds. 10 x 5 shot groups each on their own point. Tracking drift, group size and SD drift. Yes we are consistently superior to standard heavy barrels in all categories.Yes Barrel life is higher given the same conditions. As noted in an earlier post our .375 CheTac’s runs cooler than most .308’s. We were at a Sniper reunion recently and the ambient soak value was 110def F. After 30+ rounds at ranges to 1800yds our 6xc had risen to 118deg. Third party testing confirms these facts. Just adding to the mix... TACOMHQ [/QUOTE]
