Darryl, I'm taking your advice and buying a reamer and getting a smith to do the work for me here in Canada. I talked to Prairie Gunworks and they'll gladly do it,but don't have the reamer which is fine with me.I have heard the way to go is to get the chamber reamer and a separate throater. That way I can set the bullet I shoot the most to the length I want. Any thoughts or advice on this? Also,who is the best to make the reamer Manson,Clymer or Dave Kiff? Do any of these guys have the dimentions? OH!One final question, Dies! can you have these cut with the chambering reamer? Just so you know what I'm planning I'm going with a 30-32" barrel at a straight 1.250" with 6 flutes, titianium firing pin and 28lb spring, aftermarket trigger on a Mcmillan A-4 stock. Thanks for all the help so far!
