I'm curious,for those of you who don't utilize mechanical sights and always pick a spot... What happens when there isn't a tuft where you need it to be? What if the deer isn'tsome scraggley swamp buck with hair out of place everywhere and all you got is a clean flawless brown coat? Or what if it's 2min before end of legal light and you can't see a single tuft even on the mangiest Louisiana swamp buck? Where do you aim then? Not patronizing, just trying to understand.
