I have a customer who picked up a Rem 700 at an estate sale. It has a Speedy Gonzales marked barrel chambered in 30 x 45. The gun was tagged at the sale as being a 308, which is what the customer wants as he just needs it for deer hunting. Is there a demand for this barrel or should I just rechamber it to 308 for him? I can pick up a factory take-off barrel for around one Benjamin.
