I've noticed the same thing as G98. My .22 rifles HATE it when I clean them, or when I change from plated cheap bulk pack ammo to Fed AutoMatch. Takes at least 10 rounds to settle down afterwards.
Regarding .22 handguns...
I loathe my Taurus 94. Worst $250 I think I've ever spent. My only Taurus handgun and it will remain my only Taurus handgun... until I find some sucker at a gunshow to unload it onto.
In retrospect, the only sensible purchases for a sub-$400 .22 handgun are a Ruger single-six and a Browning Buckmark. I REALLY wish I spent the extra $75 or so back 5 years ago to get something other than the 94.
I've tried the Walther .22... I think it's called the P22? Too small for my hands. That thing is dinky.
