I can't agree with you YD, if the existing barrel shoots OK then there is no reason not to just run out the chamber. I have rechambered dozens of rifles, without any problems what-so-ever. One thing I can tell you that if a rifle doesn't shoot well to start off with, a rechamber will not fix or even help it, but if it shoots fine as a 260, there is no reason it won't do as well as a 6.5-06..........My concern is more about action length, not familiar with Salvage, do they run long and short actions? If so chances are a 260 would be on a short action but a 6.5-06 would require a long action.
OP.......PM me.
