I know it wasn't a CB kill, but I just harvested a nice mature doe with a 45acp 230gr Federal Hydra-shok out of my full-sized 1911. Shot was 28 paces and was DRT. This wasn't the fancy new version or +p, just the basic load. Went right in behind the shoulder and pulverized the heart and lungs - she went to sleep right away and didn't get up.
Reason I had to use the 1911 was that I hadn't finished reloading the muzzleloader after smacking another doe 50 yards past her, and this one was hanging out just a little too long! feels good to have a full freezer!
