[QUOTE="J E Custom, post: 1227921, member: 2736"] Please expand on the use of different materials for barrels. Please From a machinist view, some materials are much better than others to machine, therefore they have a better chance of being more accurate. Rifling, contouring, chambering of the free machining steels is easier on tooling and the chance of better machine work is greater. I have messed with a few of the nontraditional barrel materials and found them harder to make good precision cuts that had the finish desired for the chamber. Everything became critical and some experimenting was necessary to get everything set just right. (Spindle speed, tool location to the work, type of tools, feed rates, coolant, in order to keep the reamer cutting correctly and from damage/wear). I personally don't see any advantage to using some of these materials just for a little more barrel life and with the increase of difficulty of machining, the chance of rifling and bore tolerances not being as good as the materials that lend themselves to better machining quality, I will chose the material that will give me the best quality overall. There is a happy medium that has to be reached between longevity and machinability. being harder does not make it better IMO. I would chose the Krieger or other premium barrels made of standard barrel materials over the exotics any day and rely on the quality possibility. just my opinion J E CUSTOM [/QUOTE]
