[QUOTE="Mikecr, post: 890717, member: 1521"] I agree with this, and remind that it's relative to area applied(of bore/groove), and added to existing temperature(of bore/groove). Speed means nothing with barrel life. They don't really wear out, and even erosion is not the ultimate/irreversible killer of barrel performance. Afterall, you can set back a barrel several times to renew shooting performance. What ends it, is bore/groove constriction. This due to carbon buildup, or moly buildup, and/or lifting of bore surface from heat damage. Once these arrive, they can't be undone without damaging the bore as much. Let a barrel cool a bit between shots(~45sec),, don't let anything build up in there. Use less powder,, cooler powder,, rational pressures. Also, the 500series VV powders are the very hottest of powders out there. These are the last powders you would want to use if barrel life is really a concern. [/QUOTE]
