I don't think a few shots here and there will do any major travel changes to the deer over a shot or two. If that were the case, then they'd have no where to go come the Fall because there's so many other hunters out there shooting about everything that is legal. Sometimes I'll go in an area, after a fresh snow fall, just to see the tracks that blew out the backside to see what was in there. Most likely they'll be back the same evening. LOL!
Also, I've seen many deer at a gun range of all places. LOL! The deer there get acclimated to it over time. It's no big deal to them.
