I would go with Pecatonica. And if I wanted a straight barrel with straight cut rifling, I would go with a Green Mountain barrel. If going with radius cut rifling or round bottom rifling or a swamped barrel, I would go with a Rice barrel. The Rice barrel will be as close to perfect as you can get & a perfect breeching job. A Colerain ? you get what you get, sometimes OK, sometimes it has issues. But definitely not close to the quality of a Rice barrel. I have bought over 75 Rice barrels & on every single one the finish, bore, rifling & breechplug fit was as perfect as the eye can see.
I have used allot of Colerains & they all shot well, but have issues in either the bore or the breechplug fit on about 50% of the time. First thing on a Colerain you may have to do is rebreech it, as I think they are machine breeched, not hand breeched & about have of them are not correctly fitted. Then you have to check it carefully for loose spots in the bore. And this for sure needs to be addressed before building the rifle, as you may have to swap it out with a dif. barrel.
This happened with me on one years ago. Forgot to check the bore. Got the rifle In-the-White & took it to shoot it. Shot OK. Got to cleaning it & had 3 loose spots in the barrel. Send it back & got a replacement. Not breeched correctly. Sent that one back, breeched OK, bore OK, barrel is larger than original so had to reinlet & that was really tedious (to say the least) as I had the rifle built & sanded down & SLIM of the forestock.
From that time forward I build it In-The-White but don't touch the forestock other than inletting the barrel & pinning the barrel in, and I go shoot it right them. If I have to swap barrels, I want to do it before... I trim the forestock down & put the nosecap on, not afterwards.
