The .22's will kill deer, the .22 RF's will kill them too! My question would be why??? There are sooooo many calibers that work sooooo much better!
I understand that shot placement is the key factor, but the .22's leave zero room for error! And the icing on the cake, is after talking about shot placement, you give one of these .22's to kids or other inexperienced shooters! It just doesn't make good sense to me!
