[QUOTE="sable tireur, post: 2865734, member: 27307"] Worth is subjective and is a variable for each individual. Of course it's easier to just run out and buy an new barrel, that's common sense. When creating a new chamber in the AI form, the barrel needs to be set back. Read Ackley's directions. Here's where you can run into trouble when relying on shear numbers alone. There is a rule of thumb regarding the amount of reaming which is necessary to get down to the best metal when doing a rebore. Normally, the folks who perform this action require 0.015" material removal from the existing barrel. So your math needs to look like: .257 + .015 = .272" minimum. Be sure to read that term [I]'minimum'.[/I] One of the many realities of reboring involves what the original steel is, the process used to make that barrel and who the original manufacturer was. Some OEM barrels rebore wonderfully while other processes or formulas can leave less than optimum steel for reboring. Here's the important aspect: Call the reboring expert you choose and discuss your project with them. This insures you have the best information with which to make your decision. Enjoy the process! :) [/QUOTE]
