The "golfer" killed a deer and he was not using a legal hunting method, and he was able to keep it, hmmmm. A golf ball weighs in at 1 5/8 ounces, if you build a barrel that has an inside diameter of 1.68" and put a 12 gauge chamber in it, I bet 1300fps is possible. You'de be able to "accidentally hit a deer on the head" whenever the freezer gets low and it won't be poaching.
