I never said that a .22 would not be lethal. I said; "A .22 RF may be capable of traveling a long distance, as is the 9mm, but the energy and weight differences make the 9mm much more dangerous than the 9mm."
Now, when I proof read this comment, I made a mistake. The last caliber should have read .22 LR.
I see you've posted you-tube videos. I don't do much with that stuff because there is so much mis-information there, and I don't waste my time being an internet commando. I didn't bother to try & watch your links because of slow internet. Again, a waste of my time. I prefer to be active in the field, and have studied firearms, Safety, ammo, effective stopping power, Safety, bullet placement, downrange energy, Safety.
You obviously want to use a .9mm for hunting very small game, and nobody is going to convince you otherwise as to why you should not do it. As such, I'll not add any more to this thread. It'd be a waste of my time.
