[QUOTE="Fiftydriver, post: 891682, member: 10"] Pure and simple, bore temperature kills throat life. It really does not matter how much powder you burn in a chambering or how little, its how hot the barrel is and if you continue to shoot the rifle that will determine how long or short your rifle lasts. Some of my wildcats are pretty extreme but if you keep the barrel cool and clean, they last for a suprising long time. On the other side of the coin, if you take a chambering with much less capacity, get the barrel hot and keep shooting, it will erode a throat much more quickly then a larger capacity chambering that is properly used and cared for. Muzzle velocity has very little to do with bore wear. Powder type also has very little difference. In the end, its how hot the bore gets and if you keep shooting the rifle. This may mean you need to keep shot strings to less then three shots and allow barrel to cool between each which is exactly my recommendation for all my customers using my extreme performance rifles. Simply comes down to keeping the bore clean and most importantly, keep it cool. Now, some barrel steels withstand barrel wear better then others. The harder stainless steel in cut rifled barrels tends to offer slightly longer throat life then a button pulled barrel. Throat design also is a factor. The tighter the throat and to some degree, the shorter the throat, the longer the accuracy life of a barrel will be but again in the end, bore temp while firing is BY FAR the most important factor in barrel life. Keep em clean and cool and they will last much longer then most would ever believe. [/QUOTE]
