[QUOTE="Longtine88, post: 2890225, member: 116240"] Well I shoot lots of CF barrels. Build all of them now myself. I don't have that issue to that extreme. I can run 10 shot strings on a .2 moa shooter with 3-5 shot groups and only opens up maybe to .6 moa or so with 10 string shots or so. And some of that could be me. And that's from 20" to 28" barrels, 22 cal to 338 cal. Maybe I'm just lucky. I will add, I've never experienced anything like that with a Bartlein barrel. As mentioned.... you may be having heat transfer type equipment issues. Could be a lot of things. Tough going through the discovery of the problem. I fixed a friends rifle that did a similar string issue. After looking at it what I found was several things, a gap between the back side of recoil lug and the bedding, bedding was touching left side of recoil lug, action face was not square with the shoulder, and one bolt lug was barely making contact on the back right side. So I fixed all his issues and now the problem is gone. I guess I have a different view of it cause we deal with heat in Texas daily lol. It's 108 right now and I'm fixing to go shoot a rifle that uses a certain powder I like and I want to see the diffence in 50 degree work up and 108 in this particular combo. Good luck finding it.
