I was going to post this under the rimfire section but it mostly pertains to SD type use.
I shoot quite a bit of 'stuff' with a 22 especially during trapping season. I often switch ammo types to compare the performance. I've found a high degree of variability with every type of 22 ammo I've tried. One type of ammo may work great several times and the next seems totally ineffective due to unknown factors of application or target animal's resistance.
With these very 'unscientific' results in mind and IMHO, using a 22LR for self defense is unwise unless there's absolutely no other choice. Not saying it won't work but saying it may not work as hoped for or expected in every scenario.
I carry a little SR22 during spring and fall farm work because it's small enough to not be in the way or conflict with tractor seats. I also fully understand/expect that it's 'iffy' and would require specific targeting to be adequate. Keep this in mind as you watch those videos and gell block tests that animate targets don't show/feel/reflect the same results.
