Jeeeeeees........... the body wrench part isn't something I'd be happy with. Some of the rifles I have had to unbreech to re-barrel in the past would take one look at that wrench and laugh! They'd have the handle bent double of sheared off in no time. The best ones we had were made in the Base Workshopos machine shops and had two handles and even then, there were a couple a xxxxing great big pipe-like tommy bars to give extra leverage.

We had un breeching and breeching up down to a fine art. But be warned that if you overtighten, you WILL get a (an almost invisible) chamber bulge
