In the days of these ammo craziness I have been turning further and further from rimfire.
Rimfire was used for over 100 years as a cheap shooting alternative to centerfire... but it is not necessarily the case these days.
I can shoot and keep shooting a small center-fire without relying on ammo availability by reloading.
With just a barrel change you can have a 17 Remington in an AR-15 platform and have 4000ft/sec instead of only 3000ft/sec and depend on ammo availibility of the 17 WSM
If you want to limit case capacity the 17-221 Fireball will still fit in an AR with a barrel change and the 17 Hornet and K-hornet and great for limiting powder burn in an efficient case.
Personally I haven't fired a rimfire in the field in over 10 years. I put a way my 22 WMR when it became cheaper to shoot 223. Having stocked up on reloading supplies back in the Pre-Clinton era I have no worries about finding supplies... but rimfire is fire and its gone forever.
