Ducks and geese in the fall hunting season, rabbits during the winter and varmints anytime. One time there were a lot of gopher holes in the barnyard area which could be a hazard for cows to break a leg so instead of waiting for the critters to make an appearance to shoot my brother and I poured a bit of gasoline down their hole then wait a minute for the vapor to accumulate then flick a bic to cause ignition. If the conditions were right the explosion would shake the ground and sometimes send a couple of gophers flying ten feet into the air. Dunno if we killed any gophers or not but they abandoned the area and never came back for a long time.
Deer, Rabbits, Elk, Pheasants, Ducks, Griuse and a lot whole more. Let's say they helped fill the freezer and kept us fed. I never had a problem with killing game. Sold a number of 4H projects to the slaughterhouse, never had a problem there. 4H was a great way to learn about ecology and the ec onomics of a Rural Life.
On my Deployments had a problem with not killing. Rules of Engagement (ROE's) prohibited a number a outright legitimate shots. However the will of folks who did and still do not understand a hostile culture will always prevail over what needs to be done. AKA White Bread Suburban & IVY League at times are unbelievable
