No offense HAZ, The only thing I liked about them way back when, is the curved front sight blade reminded of a 600 Mohawk remington. My Mom worked with a guy who found out I did gunsmith work, had her bring me his basket case 66, He got it in pieces and gave it to me in pieces. I had never had one apart before, and was amazed these things ever worked. ( reputation is they do work well ) the barrel is not pinned or wedged or screwed in, it just kind of lays there in the reciever, captured by the stock. It reminds me a lot of a Marlin camp carbine in the way the stock is integral to the reciever and fire control parts. The triggers are mushy, and I admit, when I went and fired it, I just function tested it, I didn't even try for group.
But as I always say, that's why Baskin Robbins has 31 flavors.
As far as fastest cycling, I don't really see why, I think the cyclic rate would have a lot more to do with the rimfire round, than most actions it is shot in. I have had some 10/22's go full auto, and they're pretty fast.
My favorite .22, hard to say, probably my Model 41 S&W, my new to me model 18 S&W is becoming a favorite,
and my CZ .22 conversion for my AR15 is really fun. I have 2 10/22's one stock with a trigger job and 3x9 Leupold, the other for competition with a trigger job, Fajen thumbhole stock, 6.5x20 Leupold and Shilen barrel. I like them fine, only after the triggers have been worked.
The .22 I use the most, My Thompson Center Contender carbine, 16" barrel, it stays next to the back door for Squirrel duty, 62 at last count using Aquila Super Colibri, ammo. Very quiet
