If you want to shoot a BB than feel free especially if it has some significance to you like a first bow deer or something. I would not knowingly shoot onebut I guess I might/would/maybe shoot a fork or a six so I guess hipocracy is all over my shirt.
I like to shoot deer and hunt mostly public land so sightings are not a sure thing never mind shooting opportunities. I do admire those who can practice QDM but I don't think itcould ever work without some sort of antler restrcitions on public land. Treestands are like fruit here....
