If one looks at the testing done by the website "ballistics by the inch" one comes to the conclusion that shooting a .22 Mag in a revolver 6" or shorter is a waste of effort and money. Not much to be gained over a .22LR. I have a Single-Ten and think it is almost perfect as it is. (Did add a red-dot, though, because my eyes are getting quite old.)
I'm glad you mentioned that. I shoot mostly short barrels, most all my Rugers and all of my Single Sixes are 4 5/8" and a few shorter. And I've read about the velocity losses which I have no doubt are true.
We shoot marmots high up in the Sierra Nevada. Because I like the challenge of handguns that's usually what I shoot. We get plenty of shooting no farther than 50 yards or so in the rockslides. Any longer than that we switch to rifles. The first time I went, I used the .22 SS with mini mags or other brands of 22 HV. Although I was nailing them, they didn't stay anchored and could slowly crawl off.
After a couple of hits like that I switched to the 22 Mag convertible cyl and that dropped them dead in their tracks every time. So even with my 4 5/8" barrel, there was quite a difference! I've never changed back for marmots.
