My three favorite 22wmr rifles are no longer in production:
CZ 452 FS (Bolt)
Ruger 96/22m (Lever)
Taurus M72 (Pump)
CZ now makes the 455 FS, which is similar.
All three make it to the range frequently, or out an about. I love 22LR, but it lacks excitement. It has plenty of fun though. 22wmr, for me, has a bit of excitement to it.
The 17hmr was introduced in 2002. Ten years ago. Plenty of time to topple the venerable 22wmr. And yet, the only rimfire on the shelf at my local Bass Pro Shop is 17hmr. It never sold out. People have bought up all the 22wmr, 22lr, 22 long and 22 short.
Besides, does anyone really want a 17hmr handgun? I know they make them, but you really need barrel length to make the 17hmr superior. You already know how much fun a Single Six is with 22wmr.
