[QUOTE="Fiftydriver, post: 300153, member: 10"] Casspir, I have burnt out three 338 AM barrels. The first one was my original load development and ballistic test barrel. I was not overly nice to that barrel, it got hot many times for velocity string testing and just in a hurry to get load data developed. That barrel went from 1/4 moa accuracy to 1.5 moa accuracy in 570 rounds down the barrel. Some of these loads were quite high in pressure driving the 300 gr SMK to 3500 fps with the old TTI cases. My second two barrels were used with Jamison brass and they have lasted longer. They went from just shy of 1/2 moa to around 3/4 moa barrels in 620 and 680 rounds. They are both very usible long range rifles, even at 1000 yards but I decided to pull both of them and I have a Krieger barrel here ready to replace them. All of these were Lilja barrels which are famous for accuracy but they are not overly hard and tend to have their throats wash out a bit faster then a good cut rifled barrel such as the Krieger. I am predicting I will easily break 800 rounds in the Krieger barrels and possibly more. Simply put, they are not barrel friendly but for their design purpose, that being long range big game hunting. A barrel will last the better part of a hunting carreer even for a serious big game hunter. [/QUOTE]
