If I was to use a .22 LR for deer I would use a Mini Mag solid or preferably a SGB load. For body/neck shots I would use Velocitors.
I have had too many Round nose 22 LR loads bounce off the skull to really trust them. It doesn't take much of an angle. It is especially true out of a revolver like a K-22 where a lot of velocity is lost. Actually the SGB bullet desrves some penetration testing....
If at all possible, I would use a .22 WMR rather than a 22LR. The 40 grain Magnum solid loads penetrate all out of proportion to the size/velocity. The HP's will take a rib and be laying under the hide on the far side.
