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!)

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!

I was wondering if you have received your new barrel with 1x10 twist yet ? If so what do you think of it , and how does it handle the 105 bullets ?

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.

I never did order another 243. I found a 20" 260 barrel and it seems to shoot well so far with 123 gr Amax.
AFA the 308 I sent it back and got a different one. Not real impressed with it either but it shoots 110's really well.

I just ordered a 260 rem 24in from BHW I am waiting now . I was between it and the 243 , I was wanting to shoot high BC bullets the 6.5 won out . Is your 260 a BHW ?

Yeah mine is a BHW standard contour 20" 260. I can reach the lands with 120 Amax but not with the 123 Amax. I haven't done much tuning but it looks like it will easily be sub-moa. |
