Super Single Six and keyholes

[fas111]

I purchased this revolver new back in 1970-It was my first handgun purchase. I fired it yesterday for the first time in I have not idea how long. And now I know why it has been sitting in my safe all these years-Its throwing some keyholes - not every time but enough to be a concern. This is with the 22 cyl, the mag cyl seems fine. Any ideas guys?? The gun is like new, in the box with all papers even the hang tag. I paid $78.00 for it. The ammo was Remington std. vel 22lr.

Clean the barrel. Clean it really good, but don't damage it. Be especially careful of the crown.

Then, try some different ammo. Standard velocity LR in an oversize bore can cause accuracy problems all by itself...But not always. :?

So, start with the two easiest items.

WAYNO.

Thanks Wayno, bbl was cleaned before I shot it but I like the suggestion on the ammo. I'll pick up some hi velocity and give it another go.

Call Ruger and ask them, sounds like a barrel issue to me

I had keyholing at 25 yds with my bought new '75 SS using CCI Mini Mags. Didn't do it with anything else; doesn't do it with anything now. Just a fluke with the old CCI's. I seriously doubt it's a barrel issue.

I'd buy a box of CCI Mini Mags and a box of WW Power Points. I've found them to be a good starting point.

I'm with Wayno on giving that barrel another good cleaning.

I'm guessing the barrel might be "leaded," where the grooves are filled with lead. I had a Smith 617 that this happened to. When I brushed out the bore, I got lots of slivers of lead out of the grooves. Most of them came out in chunks about 1" long.

Usually leading is from high-velocity rounds. Remington Thunderbolts are often blamed. I wouldn't expect that the Standard Velocity loads would lead badly, but you never know.

Do you have a kid or someone else who might have "borrowed" the revolver, filled those grooves up with lead, and then snuck it back into the safe?

Ruger is known to have drilled through the barrel with their front sight screw on a few of those. Maybe you've got one of them?

Also, .22's are the most make and brand sensitive of any caliber I know of. Since you can't tweek with handloads, buy several different boxes of 50 . See which one shoots best. Then, buy a pile of it, and be happy !
