got a couple of gov't profile DD barrels (12.5 and 11.5) coming, CHF 1:7" all that, what kind of accuracy are people seeing out of them? I'll be hand loading 69-77gr match bullets in one, shooting factory steel match hornady from the other
I have a 10.3 DD CHF barrel. It shoots sub moa very often. My best 3 shot group is .667 CTC. This was with Black Hills 77gr. Have shot many sub moa groups. Thought maybe I got lucky and got a really good one.
Although it is merely my personal preference, for top end barrels, my first choice would be single point cut rifling. My second choice would be hammer forged. However, for hard use barrels, I really like a chrome bore. With that in mind, the hammer forged, chrome bore by DD is a pretty good choice.
I've had 2 14.5 DD pencil contour (.625 gas block) midlength gas that both shot 1/2 MOA with 77gr SMK @ 2.26 in Lapua brass, fed GM small rifle, and 25gr TAC.
