Think a small set screw would help stop the rotation, or would the hole weaken the frame too much?

Think a small set screw would help stop the rotation, or would the hole weaken the frame too much? I have a Jim Stroh built Colt Bisley (1905 IIRC) in 45 Colt with the following work: Line bore 32 cylinder to 45 Colt Fabricate line bored 45 ACP cylinder Fabricate 45 caliber barrel with Bowen dovetail front sight, drilled and tapped for scope bases Action work Mill topstrap for installation of S&W rear sight You mention a small set screw to lock the barrel in place in the setting of a barrel mounted scope, which this gun was built as. Stroh, being the master revolver smith that he was, used the screw that held the front of the S&W sight tang in place to also lock the barrel in place. The front screw sits over the threaded portion of the frame, and he drilled through this and into the threads of the barrel. Not a direct answer to your question, but some food for thought and IMO evidence that it wouldn't weaken a Ruger frame to any meaningful degree. Here we're talking about standard pressure Colt loads, but also a thinner frame portion with poorer metallurgy than a modern Ruger.

I was thinking through the side of the frame. But going through the top would be stronger now that you mention it

Jim pinned a barrel for me on a 629, no reason anyone could not on this. Todd a pic would be nice sir.

A set screw would work. I think a cross pin is a better idea. But an even better idea would be to just loctite the barrel with either red or green loctite. You could even set the barrel cylinder gap while you have the barrel off. Just my 2 cents. There's more than one way to fix this problem.
My father has a 45 Hunter from the first run of these revolvers, and mine is from this latest run. We haven't had the barrel off either gun yet. IDK if the pitch is different between the two guns like mentioned earlier. Both guns have .006-.007 barrel cylinder gaps, so taking the barrels off to correct this is in our plans for the future.

Well he doesn't want to put the NOS Redfield mount on this as he's afraid (rightfully so from experience I suppose) the frame would break a tap being so hard. Now what? The factory rings? I do like the way they do not pull the scope back to obstruct the hammer. Ronnie? The frame can be tapped......Emuge is the answer.......I’ve seen 60 RC tapped. It was on a mill with rigid tapping......but the frames are nowhere near that hard. It was sort of surreal........high pucker factor the first time. Just went in and out of 16 holes one after the other. But Emuge has a tap for every situation.......got to buy the right one. I just got a 41 Mag hunter (not a Bisley sadly) to build a 414 in a max frame with the hunter barrel. Now I heard they have different sized threads on some of the hunters.......so I’m thinking to put Bisley parts on the hunter and frame mount the scope on the max framed 414....... Thoughts and ideas?

It only took three months to find the factory rings
