[QUOTE="trebark, post: 564012, member: 19172"] Heat is the enemy of barrel life. Often you will hear discussions of one cartridge providing more barrel life than another. For instance, a 6.5x284 is a known barrel burner whereas a 308win is not. This is because the 6.5 burns a bunch of powder at a high temp and pressure. This erodes the throat. Even with a barrel burner cartridge, you can still get decent barrel life out of the cartridge by not 'abusing' the barrel - which is to say, not shooting long continuous strings. The guys that burn barrels out fast are competition shoots that shoot 15 or 20 shot strings in a short amount of time and do it on a regular and almost continuous basis. If you just shoot a couple of rounds and let the barrel cool down, it should not have a terrible affect on your barrel's life. Then of course, you have to determine what does 'shot out' really mean. For a benchrest shooter, the loss of .25moa is shot-out. I have a friend that has a 300winmag with 8000+ rounds down the barrel. It still maintains a level of accuracy that he wants. Is it shot out? probably. Does it matter to him - no. [/QUOTE]
