I have used the TBBC bullets in some of the larger calibers with good results, so I'd expect them to give the same good penetration and high weight retention in the .22 caliber. Another good bullet is the 64 gr. Winchester Power point, if your gun will stabilize them. Remember that this is a little bit of a "stunt", in that you have almost no ability to take certain shots/angles. Got to wait for that broadside through the ribs presentation and, even then, you may have them run a ways. For Hogs, I think I would limit myself to head shots. Roskoe.
