Spun up a new barrel for my .300 Ultramag. Stainless, button rifled in sporter weight from a popular barrel maker. Muzzle end had a tad over .015" TIR when finished. To really live life dangerously I fluted the barrel after chambering. I wanted to index the flutes so that it looked symetrical when sitting in the stock. Took the rifle to the range one afternoon to stretch her legs out to 600 yards. We have to shoot on a verification target before engaging the 600 yard target. Two shots at 600 to adjust/verify the scope setting and then a ten shot group that made me smile. Went to put the rifle back into it's case, burned a finger on the barrel. The barrel was hot (fired twelve shots in less that ten minutes)!
PLEASE don't tell that barrel it's suppose to walk shots when hot.
