So if you miss on the first shot or if you wanted to stay and try to kill a buck after shooting a doe....you clean it in the tree or just go home and clean it instead of keeping on hunting? That has always been my issue with the "sighting it in with a clean barrel" argument. It just ain't practical from a hunting standpoint when hunts often span long weekends, consecutive weekends, etc. If they shot the same on a clean barrel versus a fouled one it would be super easy to deal with one but they don't...and that's why they suck regardless of which powder you put in em!
