does Ruger use on SA revolvers? Its been my experience that there is; Tight!, Damn Tight!, Gottendammer Tight!, And 'Ruger Tight'!

Probably use a good thread lock also.

barrels. Old mauser 98s and ruger 22 marks are the only gun types i have turned the shoulders off the barrels to remove.

Ruger SAs are known to sometimes have barrels screwed in so tight that they are actually swaged down slightly, creating a constriction just ahead of the forcing cone. I've heard of several guns that showed poor accuracy due to this, most often .45s. Don't know how they accomplish this - they must have a hellacious machine or an ex-Alabama lineman with a BIG wrench installing barrels.

You cinch that bad boy down till your face is red, your knuckles are white and your balls are blue. It ain't coming loose after that.

that had a loose place right where the barrel screwed through the frame. This was a 22. Always leaded the first inch or so and shot about a 3-4 inch group at 25 yards. You could slide a oiled patch down the bore and when it entered the frame it was super loose. Sent it to Ruger and they changed the barrel and all was well. Shot nice round 2 inch groups or less at 25 yards.

I have a question about this.
IF it is that tight and it causes a deterioration of accuracy why does Ruger continue to do it?
"Lets produce a product that has a noticeable flaw that gets us bad press and continue to do it after it is publicly recognized" does not seem to be a part of a good business plan.
Surely the equipment that does this has sensors that detect the issue that produces bad guns.

Probably manufacturing tolerances and liability.
Ruger will accept some barrels being so tight that the gun loses accuracy, as long as no barrel will ever loosen even if it's torqued to the low value of acceptability due to tolerance stackup on the dimensions of the barrel shoulder, threads and frame dimensions.
