You mean .22mag mags? Or .22lr mags?
I have 24 Weatherby MK XXII mags, 4 are 5rd and the rest 10rd
Nah- just the boring old .22LR mags.
When ammo was readily available, those were the ones that saw the most wear and tear. I liked watching the kids empty 25 round mags... but I hated loading them again.
