[QUOTE="Broz, post: 991592, member: 7503"] I had a very nice lengthy conversation with Mr. Pedersen today owner of CBW. What a great man to talk with, and very meticulous and well versed in what he does. We talked in length about possibilities for what could result in velocity gains that are being seen here. He does hold some very tight tolerances (min. spec) and has some very good processes to produce a high quality barrel. So much that I plan to order one. He also has done some reduced land height rifling he refers to as "shadow rifling" and has been doing it for some time. We also talked about the possible adverse effects of this process as well as the velocity gains. But the barrel in question in this thread had NO special rifling or chambering other than the longer throat length to seat the bullet out farther. But this barrel was indeed held to CBW's very tight spec and could very well be at .3382" all the way through. Quality machine work for sure. But we agreed nothing that would cause the kind of velocity gains that are being seen in this thread or nothing that would lead us to believe that anything would allow larger charge weights. In the end we agreed , no free lunch, and velocity is for the most part a direct result of pressure. But I am thankful for this thread as after learning the process Mr. Pedersen uses I do want one of his barrels. I believe his process could very well produce a very accurate barrel. FWIW Thanks Jeff [/QUOTE]
