Well Pastor,I too prefer my small game to be headshot with a rimfire.That being said, how much shot you put in your target is a function of how your gun patterns a given shotshell and the range at which you acquire that target.Certainly more shot payload and powder will give you more effective range. Also, if you have a close shot with a fat load ,you don't have to center your target in the pattern,so as to reduce damage. Kinda like "barking one" except with a shotgun.Early season,leaves on the trees,or moving targets,extended ranges, I'll take the more powerful shotshell every time.
