I'm sure my first ever handgun kill was probably a ground squirrel or a chipmunk, can't remember. First big game kill was a whitetail buck in Idaho a couple years ago. There is a pic in my photos. 6" GP100 357, 158 XTP HP @ 1500 fps. Recovered bullet up in the neck after 16-ish inches of penetration, XTP still weighed 141 grains.
