A revived interest, not at all. I never lost the intense interest in it. Fact is, the lowly .22LR is my all-time favorite caliber in pistols, revolvers, carbines and rifles. They are cheap alternatives for trigger pull practice. They are quiet enough, and potent enough to engage in varmint hunting out to 200 yards. What other round can be had for the unbelievable price of $99.00 for 5,000 rounds (Remington Thunderbolts)? That sounds like a lot, but given how quickly my daughter fires them off, it doesn't always last long.
In terms of a bullet in a pinch, my uncle hunted his first whitetailed deer with a .22LR. This was back in the days before the caliber restrictions. As I recall it, he said it took 5 shots.
So, yeap. We have a few .22s:
