[QUOTE="VinceMule, post: 3044814, member: 122164"] Letting it cool in between shots will help, I use 50/50 water and alcohol during the Summer months, apply with a washrag till the solution is dripping off the bottom of the barrel, cools barrels so quickly, you will not believe it. The real answer to the question lies in how much heat a particular powder generates during ignition. There is a Heat Index chart of powders that ranks them in how hot they burn. This Heat Index chart is NOT the Relative burning rate chart. The N500 series of powders are among the hottest burning powders on the market today. Shocking that Varget, IMR 8208, and H4895 are not too far behind. I learned a very hard lesson with a 220 Swift shooting N550 hunting coyotes. With these very hot burning powders, they normally wipe out 9" of the barrel from the throat forward. All of us have various amounts of disposable income on this hobby, so you can get a wide variety of answers. [/QUOTE]
