I've got it soaking in kroil, will hit it with the jb tonite. I have done that before, and it seemed to help for a while.
I just hate rifles where you're constantly testing to make sure the accuracy is still there. This barrel was never a tack driver to start with, the best groups were with the 75 gr sierra's, but generally speaking it's a 1 moa barrel (5 shot groups) at best. With the odd group doing much better, but it's pretty rare. I think it might be time for a change.

The dreaded "Carbon Ring" may be rearing its ugly head. I'd follow Greg's advice, and see about getting a carbon solvent into that chamber.
My .243 didn't last 1000 rounds, before the accuracy fell off. Partly because my MV was running on the high side, and partly because I once got a little too enthusiastic on a target rich prairie dog hunt. It was a case of "Ok - just this one more..." (They wouldn't leave me alone, I tell you!)
A problem thoroughly understood is always fairly simple. Found your opinions on facts, not prejudices. We know too many things that are not true.
Well I heard from Andy via email tonight, he asked for specs on what barrel I wanted. I want the same thing only going with 1-10 twist (like he suggested to me last summer when I ordered this one). So when he gets back to me with a cost I'll probably be placing an order! Excited again!
If you didn't get rid of the 308 barrel. Try imr8208x I shot a 3 shot group at 100 yards that measured .17 after subtracting the bullet diameter it averages 2475 fps . That is out of a BHW 18 in barrel with a mid length gas tube.
