I am working on converting a carcano to 7.62x39 (finally getting started!), and was wondering about threading my barrel. I bought a while back, a chinese sks barrel that is intended to be pinned into the reciever. I was wanting to thread this and the inside of the existing barrel stub so that it is easier to headspace. I am leaning towards the lock nut system used on the savage rifles. How thin can the chamber area be before it is too thin? this barrel is .750" at the breach, but cutting threads into this is going to weaken that area a bit. the other option is to bore out the existing barrel stub and press fit that into the action, holding it with loctite (or brazing it), and pinning it for good measure. after threading I will only have a wall thickness of .113" if I thread to a standard 3/4-16 pitch. is that enough?
