Bought a used savage barrel and it is about 1/2 inches shorter and the threads extend into the factory stampings. I think this barrel was set back and rechambered - same cartridge 220swift. Is there any other concerns than that the barrel threads on well and was chambered properly. If it was "shot out", would this typically have restored it. I am not expecting competition level accuracy and probably will never send 300 rounds thru it. I know the true test is to shoot it. Seller offered to take it back if I am not happy with it but I think I want to shoot it.
