[QUOTE="Hugnot, post: 2193851, member: 115658"] Barrel steel, including stainless, quickly forms a coating from chemical reactions upon being exposed to heat & like the paper says this makes for more wear. For stainless the chromium reacts with oxygen upon heat & the more heat the faster the reaction. The formation of the coating is erosive. Imagine, shooting NRA HI power with a .243W (107 Sierra MKs) including rapid fire & 20 timed shots at 600 - it quit half way thru season but .308 finished season. The .243W - got hot enough to make your fingers stick to it. As far as barrel break in - I clean after every 6 up to 1st 30-50 at range while sighting in & fussing with loads. At least, throw a wet towel over the hot barrel. I like a gap between stock & barrel, enough space for a doubled up wet paper towel. Cool air inside barrel works faster. [/QUOTE]
