I think I am experiencing the Old Revolver Blues. I have an H&R 929, a double-action swing-out .22 LR nine-shooter. It's from 1969. I love the revolver.
Trouble is, its crane is showing its age, and I don't know how to clean it without bending and possibly making it even looser. I'm really gentle when I shooting it, but I can't get the bore brush into the chambers without pushing pretty hard. I can hold onto the cylinder while I use the bore brush, but then the weight of the frame is torquing the crane. I can hold onto the frame, but then then friction of brush against chambers is torquing the crane. The same goes for bore patches, unless I cut them so small they're just tickling the insides of the chamber.
Should I be trying a different cleaning technique, or get a .204 caliber brush, or quit worrying about my crane getting loose? For a while my plan was: clean barrel, frame, and outside of cylinder but not chambers, but I realized that will make extraction stickier, necessitating punching the ejection rod harder ... same problem.
I am assuming there's no real economical way for a gunsmith to tighten a loose revolver, at least one that's been out of production for so long. True?
Some facts I learned about the H&R 929 today:
The HKS Speedloader designed for the Taurus 94 does indeed work for putting .22 LR into the revolver, but not for .22 Short. The speedloader doesn't mate to the cylinder at all; with .22 Short the ejector star keeps the loader so far away that the bullets don't enter the chamber at all! Not a big deal; I never buy .22 Short but I steal my buddy's.
