Hi all and thanks in advance. I have a Herbert Schmidt SA 22lr MOD 121 and have a chance to purchase a MOD 21 Cylinder in 22 magnum. Would the 22 mag cylinder work on my model? Is there a bore size difference between a 22 lr and a magnum. Any wisdom would be great!

Based on the interchangeability between the .22 LR cylinder/.22 mag cylinder on the Ruger "Single Six" - with the same barrel/bore, I would think you'd be fine. My concern would be about the timing of the cylinder you are buying - if it's not spot on, you'll get a bit of splatter coming out between the end of the cylinder and the back of the barrel. I did learn that if you shoot LR ammo in the magnum cylinder, the accuracy takes a hit.

Yes there is, but it's inconsequential. .22 Magnum is .224" bullet, and .22 LR is .222. I believe all the convertible revolvers are sized toward the .22 Mag, and most find that it shoots a little better with the Magnum cylinder.

Why would you shoot LR out of a Magnum cylinder? Don't you find that it splits cases?

And I wonder if that lead splatter might be caused somewhat by pushing a bullet out of an oversize chamber and into a slightly oversized forcing cone?

I didn't do it on purpose - I had previously been shooting mag ammo with the mag cylinder and neglected to change back to the LR cylinder, when I was done. Some time later, I was shooting LR in it and realised my oversight, when the accuracy had gone for a crap. - didn't split the cases. My comment about timing, was not specifically for this swap - I had shot another guys revolver and noticed that there was a bit of splatter coming from it and was subsequently told, that he had installed a cylinder from a different gun (same make and model). I just figured that the timing might not be spot on - my opinion, only.

Ah, I see. I believe that may be a concern with some revolvers, but I think that most of the better made ones are pretty interchangeable.
