I made my first kill with a .444 marlin on a button buck that dressed out at 80 pounds. I had a dog that was bigger than that. Remember, you can't make them
too dead.
I also use surplus NATO ball ammo in 7.62 from my Garand. Specialized hunting rounds be damned! If it was good enough to kill VC it's good enough to kill Bambi.
Let the flame war begin!
