though it is a tough call i have ben very fortunate as to always be afforded the opportunity to take good clean shots. my dad shot a deer a while back and same story but i carry a Glock 9mm on me during bow season. i carry it concealed and un-loaded. i only load it when going to and from my stand and when tracking a wounded animal. it is against the law however i don't think the local PD or DEM officers would ticket me as i am only doing this for safety from coyotes and hey should a wounded deer be suffering i would much rather end it instantly. I have been practicing this for a very long time and have never had anyone question my practices. hope it helps and hey don't beat your self up over it. you reacted with what you thought at the time would be the best option and now you are more informed should this happen again.
