I've pondered this question a lot. When a post asks for a "pet load" in a given caliber the answers are usually a full bore load. My handgun skills don't allow me to take long shots so lets say a deer might present a 30- 40 yarder. I've always felt that if a bullet penetrates, the energy left over that expends it's self in the ground beyond is wasted. I have a friend that guesses around 950 fps with soft lead bullets gets the job done. Anyone have any feelings on this at all?
