[QUOTE="Brent, post: 27564, member: 99"] RR, I wouldn't worry too much about it, you said accuracy was still plenty fine right? 4mesh has been telling me lately about his take on "so called" worn out barrels, think "fine wine", that's been his findings. With all the talk about short throat life and such on overbore cases, I've been all ears for a while now too. The 6.5 WSM, 30/338 Lapua Imp and so on... I'd use some JB on it and keep shooting it, according to 4mesh, it should just be starting to shoot good about now and only gets better. [img]images/icons/wink.gif[/img] I use JB frequently, almost every cleaning, the throat on my 300 Ultra is a little rough, but it still shoots great. I can't see where the copper is accumulating the most, no bore scope. How can you tell yours is coppering worse in the throat area than the rest of the bore? The 30/338 LI that's getting done right now is using a 11 twist 3 groove Lilja too. When it stops shooting great, assuming it will [img]images/icons/grin.gif[/img], *then* I'll start worrying about rebarreling, if in fact that's even the problem. Good luck.
