Magnum Cylinder in Bisley

1174 Views 13 Replies 8 Participants Last post by  Uncle Howie
I have a Bisley Single Six in 22LR. Can I buy a Ruger magnum cylinder and install it or will I need to have it fitted by a gunsmith? I have located a cylinder that has dimensions slightly smaller than my current 22LR cylinder.

Well, I took the plunge and have bought a Ruger, unfluted 22 Magnum cylinder from a man on the Ruger Forum. If Heritage can make their magnum cylinders to fit across the board, surely Ruger's QC is better than theirs. We will see.

Was your Bisley convertible.? They have a larger bore than a standard.

Cool. Looking forward to your shooting results and some pics, too! ;)

As far as I know, no Bisley revolvers were convertible.

All Ruger Single Six barrels made since about 1960 are .224

Bought a 22 WMR cylinder on the Ruger Forum and it fits like a glove. Timing is spot on.

I have a 1983 vintage SS that was a gun show bargain due to a bum rear sight, easily fixed. It's a great plinker and I often use it for training new handgunners.

On a whim I got a spare .22 WMR cylinder which dropped in as easily as expected and appears to time correctly, with no spitting. However - while the .22 LR cylinder gives nice groups on targets, the .22 WMR cylinder throws patterns! Seriously - 6" "groups" at 11 yards is horrendous! Any suggestions as to diagnosing the problem?

Not sure what I would do. A thorough examination of the bore would be my starting point. Then, I would buy the same brand ammo, same bullet weight if possible, pull one or tow of each and mic the bullets. If you are careful, you can replace the bullets if you didn't spill the power. I would swap the 22LR bullets for the 22WMR, maybe 5 of each and see if that produces different patterning.

Let us know.

HOW does it shoot ?

I would start with having the the cylinder individual holes measured next I'd look at the gap between the cylinder and the bore. then I'd have someone with a range rod check alignment between the bore and cylinder it could be off after that I'd look at the forcing cone it might be too tight for the 22 WMR.

I desperately need to take it out and see. Will update this thread then.

Ruger has used the same barrels on all .22 Single Sixes since 1968.

It appears that you are suggesting swapping bullets between the .22LR and .22WMR. Do I understand your advice correctly?

That’s going to be pretty difficult, since the .22LR is a “heeled” bullet, and the .22WMR is not.

I’d start with a thorough cleaning of that .22WMR cylinder. Then I’d start measuring the throats, checking it with a range rod, etc., like S/SP suggested. 👍
