Tinker,
I have a super magnum william evans, with rachet rifling and could do a cast also. Who were you thinking of having cut the barrells? Dan Peterson comes to mind. Another interesting aspect of the paradox barrels is the swamped affect in the barrel profiling. It must be key the getting a proper handeling gun. An interesting thread. I've just purchased my gun and am interested in working up some loads for the old girl. Its a shame such a lady actually apears to possibly be a true virgin. If not, she has seen very little use. Fun stuff.
