twist rate, bore dimension???

[G.T.]

Thanks for the excellent answers guys, I knew I could count on you fellows for some good info... The gist of the project is that I am currently working on some outside of my skill set projects, with a fellow enthusiast, and may have relatively inexpensive limited access to a CNC machining center, and the skilled laborer to run it... All on a friendly basis... I thought if I could procure quality blanks relatively close to original, I would have a small quantity of new barrels profiled and short chambered for a quality replacement barrel... Caliber, length and profile are all still up in the air... I'd guess, all or any is possible??...As mentioned on the forum, recent barrel offerings may range from right on to impossible to install?? I may never get passed the dream stage.. but I know for sure, you can't do, if you don't plan.... ... Thanks guys... all opinions, suggestions, are appreciated.... Best to you guys, til...lat'r....GT
