[QUOTE="Michael Eichele, post: 338095, member: 1007"] I have found that factory barrels chambered in hot calibers actually last longer than custom barrels. My theory is that when you have a rough barrel it actually improves as it smooths out a bit during break in, shooting and cleaning. When you take a perfect barrel with a super smooth finish, it can only go downhill from shot number 1. I have not fired enough bullets through my edge to give a number. What I can say is that when it was a 300 RUM, the throat was in bad shape in less than 100 rounds. The barrel in general was in really bad shape after 500. Accuracy, velocity and consistency changed from day to day. To be fair, I was hot roding it. It was also a cut rifled barrel which I hear dont hold up to the heat and flame as well as a button pulled barrel. I dont know that for a fact but after having a button pulled 300 RUM and a cut 300 RUM I would say that is a fair assumption. 1100 rounds was the magic number for my Lilja. It also in the beginning showed signs of throat troubles within a couple hundred rounds. After 180 rounds through the edge, I am still running the exact same POI, velocity, group sizes. I have not bore scoped it since 110 rounds but after 110 rounds, the barrel looked flawless. The throat was perfect and there wasnt any heat checking. I am fairly confident that the life of my "hot 338" will be considerably longer than my "hot 300". Just my .02 [/QUOTE]
