I'm in eastern VA, where deer hunting with hounds is common. It's in the culture here. I'm glad to hear that you don't see it in the mountains.
I have two friends that used to hunt with dogs and they each had close friends get shot. They were unwilling to speak about it and I never could figure out who the shooter was (might have been my friends). Many, many, many of the hunt clubs have had a member shoot another member within the last 10 years. Some have multiple shootings in a year. Fortunately, most are with buckshot at long range (over 100 yards) so the pellets rarely kill. I think that's why you don't see it in the news. The hunt clubs try to keep it quiet. These all accidents.
A friend of mine is in the club where a member shot another last year and the victim died. It was about 15 miles from my house. Three guys were walking away from their trucks. The guy in the back dropped his gun and tried to grab it before it hit the ground. He accidentally fingered the trigger and killed the guy in front of him. Apparently the safety was off. Again, it's in the culture of eastern Virginia.
It also doesn't help that we have 6 deer tags with 3 of them being any-sex. This means that the shooter doesn't need to positively identify the sex of the deer before shooting. And in Virginia we are allowed to shoot 2 per day. If it's brown it gets shot at. Typically they are going to shoot a full load of 5 shells. I think you get the picture.
