public range
There is a public shooting range near me, and I often scavenge brass there. Once upon a time, the pickings were good, now not so much. They even sweep up rimfire for scrap. Anyhow, one of the spent cases I'd see in abundance was .22 WMR.
The .17 HMR landed with a big splash, but there are a lot of those old .22 mags out there, that were sold affordably, and people shoot them, or at least used to, alot.
I always considered the .22 mag a "poacher's caliber" and never gave it much credit. Then my Dad's long tubed Single Six came my way after his passing, and for grins, I put the .22 WMR cylinder in it. It's not a plinker, one doesn't shoot it high volume. But as a field gun, I believe it's a better killer on pests, and shoots a bit flatter (not that I am any sort of long range handgun guy) than the .22 lr, with out making the jump to noise and bulk of say .38 spl or a 32-20, .32 HR mag. The .22 mag cylinder is staying in the Single 6.
