Well for me I got a clue early and figured it out in about 140 rounds. I have since found another barrel maker that uses Benchmark or X-Caliber blanks and does his magic in a timely manner so with this "dragging ass" issue with Criterion leaving me hanging (but they got my money) I'm going to switch brands. Currently having 2 replacement barrels made and hope to get them this week sometime.I've had one bad Barrel that I could not get to shoot. 8 TWIST 6.5 in 6.5 X 284. Best I could come up with was 3/4 of an inch at a hundred. Tube was mounted on my 1000 match gun.. it's shot like a hammer with any of my Dasher barrels but whenever I screwed 6.5 Barrel on it was a dud. Sent it off to my gunsmith so he could scope it out. No problem found. I had him cut an inch off the end of the barrel and re crown.... still no joy. Sent it back to the manufacturer and they gave me a new one. They were satisfied that I did everything I could. Their response was sometimes some barrels just don't shoot. It took me nearly 400 rounds to figure that out
Well I guess it's a case of "Better Late Than Never". I'm glad they finally sent you something and I truly hope you can get back to the match schedule you want. It is not easy to get past that kind of Customer-No-Service.Update as of 10-14-20
Out of the blue a barrel showed up on my door step? It's a replacement for the bad one. No notice or nothing just here it is. Oh well I least I got it, now to decide if I'm going to shoot it or sell it???
Use new brass for your barrel. Not doing so will just cause problems.It looks good inside and out, I did decide to shoot it so we shall see if the accuracy is there. Got two matches left this season so i'm going tonight in the rain to break it in and see if the loads work as they should.
Never mounted it, still in the box for a back-up. I had my smith check it a long time ago with his bore scope and it looks perfect inside so it should be good. My priorities changed in 2021 and I went all 12 twist and lighter bullets 68 to 80gr was working on loads for a batch of Bart's Dominators until winter hit...How did it end up shooting for you, @Lefty Trigger?
Yeah I just got a new Bartlein like that. Just makes one hole. Sucks because I can't tell if the bullet came out and have to pull the bolt and look down the barrel every time.I have a Bartlein bbl, I would've been happy if it shot 1/2 MOA, but no its keeps shooting all the bullets in the same hole.
