[QUOTE="Gerard Schultz, post: 947219, member: 51"] Agreed. A big enemy of barrel life is heat. Never shoot a barrel hot and life is increased greatly. Another factor is gas that leaks past the bullet at any stage. The more one can limit gas leakage, the better. I have a wildcat based on a 270 case and necked down to .224". I have been using a 40gr bullet at 4700fps for years now and the rifle used to be a 220 Swift until it was converted. It had about 2500 shots done while it was a 220 Swift and it has done a further 500/600 shots as a hotrod. The barrel will still hold half a minute, as it did when I built it. It has never been shot hot and it has fired about 100 shots with bullets other than HV drive band bullets. [/QUOTE]
