I have a strong preference for cut rifled barrels. Krieger being at the top along with Brux, and Bartlein. I also prefer the plain jane 4 groove over the newer 5 groove style. I have only tried 1 of the 5R`s from Bartlein and it copper fouled. I would go about things differently. I`d send the action to Greg Tannel, Gre/Tan Rifles for the action work only. He is amazing on 700 Remingtons. His full blueprint is $500.00, but you get a full blown custom quality action. Just skip the light weight firing pin all together. There is much to be said of the mass and impact of the fire control. Order your Krieger barrel, immediately as wait times are long, or see if Grizzly Machine has a Bartlein in stock that you can use, if you call Brux, Norm or Ken may answer the phone and let you know how long the turn time is. Find a very reputable smith to assemble the parts, they take longer than your local guy, but the end project will depend on the craftsmans hands who indexes/threads/crowns and chambers your barrel. Grizzly Machine also carries PT&G reamers in stock if the specs are something you like. If not I can highly recommend JGS Tool for a reamer. They are $200.00 not including a headspace gauge.
