[QUOTE="Fiftydriver, post: 189641, member: 10"] Not trying to start anything but the comment about having 1000 rounds down a 338 AI barrel with no heat cracking or throat erosion is simply laughable in my opinion. You will see heat cracking in half that many rounds no matter what barrel you use. This does not mean it will effect accuracy all that much but it will be there, no way around it. At 1000 rounds in this class of chambering, you WILL have heat cracking and you will also have throat erosion, again, no way around it. Not flaming but this comment is a bit silly in my opinion and not a realistic way to look at barrel life and this class of chambering. I have chambered big 338 rifles from the 340 Wby, 338 Jarrett, 338 Lapua, 338 Edge, 338-378 Wby, 338 Kahn and 338 Allen Magnum. There is not one of them that will not at least some amount of heat cracking after as few as 300 rounds in most brands of 338 barrels. That holds true from the softest which are the button rifled barrels up to the very hardest barrels which will be the cut rifled barrels. THEY ALL will have heat cracking after as few as 300 rounds. At 1000 rounds, there will most certainly be heat cracking and it will be significant with any of these chamberings. Just want to throw a bit of reality out there for some that do not know better. There is no way to avoid heat cracking and the 338 AI certainly will not prevent it in any way. JMHO, Kirby Allen(50) [/QUOTE]
