I have a model 650 with both the 22 mag and 22 LR cylinders. A few years back I picked up another stainless 22 LR cylinder, and am trying to decide where to use it. I have another 650 and a 651. I like to have the dual cylinder option and have it on several guns (like a 17 with an extra 48 cylinder), so common sense says to put it on the 651, but I think the 650 might have more value?

If you already have a 650 with both in addition to both a 650 & 651 without, I would add the extra LR cylinder on the 651. Then you would have both sister models with both cylinders. That would leave you with an extra 650 with just the WMR cylinder. You could use that 650 with the new Win Subsonic loading to give you low blast/recoil/flash for a great trail/kit gun

Do you different points of impact with dual cylindered Model 650?

I would always recommend adj sights on convertible guns, therefore advise putting the extra cyl in the 651. Especially since there optional cartridges for the mag cyl and so many choices in 22 LR.

Lately I've been shooting 22 WRF in my small frame 22 magnums. They're cheaper, just as accurate as Subsonic Mags, and as nosho posted, "low blast/recoil/flash".

I also shoot sunsonics in the LR cyl which can benefit from an adjustable sight.
