I have seen deer spook from dove hunters at over 800 yards away and seen them come into the pond that we were shooting at. Just because you are shooting and see deer doesn't mean that you didn't push others away. Heck, we were blowing up tannerite and had a doe and yearling come by at about 400 yards down range.
We shoot on our place in a designated area, but I wouldn't want the range to be set up near my stand and wouldn't feel confident hunting a stand that someone is shooting 3-400 yards away at targets. Our place is 10k acres, but I wouldn't like it, during deer season, if I was on a smaller place.
Not saying that it does scare them away though and with enough shooting, the deer will get accustomed to it. I used to hunt down around Proctor over some peanut fields. The ranchers would set off cannons in regular intervals to scare the deer away. While they could sure make me jump, the deer got pretty used to them and wouldn't even flinch. Step on a branch and they would run like the wind
I would say "do what you feel comfortable with."
