Biggest pop can I ever saw get shot at was a "fi'gall" - that's a five-gallon metal canister of coke syrup - my family's 45/70 (from the Spanish-American war era) blew a softball-sized hole in it! (Fired not by me - the think kicks like a mule, and my brother was worried it would knock me over!)

Me, I prefer hunting sand banks - they're easier to hit than blades of grass! Granted, there are usually targets set up in front of said sand bank, but hey, I hit something, anyway!
