I've only recently started hunting with a single shot, taking a couple whitetails, a mule deer, a few Sitka blacktails, and most recently, a pronghorn. I've always been fairly conservative in when I choose to pull the trigger, but may be a little more so, since I began hunting with single shots and drillings(which from a rifle standpoint I also put in the SS category). As I "mature", I've found that I, like Grasshopper has mentioned, care more about how I kill my game, as opposed to how much game I kill.
