[QUOTE="joe0121, post: 737805, member: 26058"] IMO, "they" say useful barrel life on a 300 WM is 2500 rounds. I have 3k through mine and still pull off 1/4 MOA groups. Personally I think the issue with barrel life is over cleaning and unproper cleaning. I also recently started HBN Coating at around 2700 rounds with great results. Free bore is the same as when the Rifle was new. I Push 208 gr Amax at 2890 FPS out of a 28" barrel. Thats with about .020 jump into the lands. Bench rest is most probably a different story as you fire a lot of shots close together which make matters worse. Bottom line though for what it cost to feed the big .338's a new barrel will likely be the cheapest part of the equation anyways. [/QUOTE]
