I think the shotgun zone is in place due to population density and maybe even hunter density.
Where I hunt in Zone 3 the opener was as usual, a zoo with drives and LOTS of multiple shot volleys. Between the first shot and 11 in the morning I’ll bet I heard no less than 400 shots fired in the surrounding area. The late afternoon on the opener had more of the same. By comparison, the second day of the season I heard seven shots all day….same exact area.
What I noticed sitting on stand all day is the up-tick in road shooters this year. Where I sat this year I saw two different pick-ups stop and people bailed out and shot at deer that were downhill from me. Both of these instances occurred on the opening weekend, so not much has changed in the illegal hunter department. I called the sheriff’s department on both and gave the color and brand of vehicles as well as specific location. There was no way to get a license number. Thru the week both vehicles were seen back making the rounds each evening just before dark. Not one CO vehicle was seen during the whole season. Not one. And this in an area where we could always count on being checked at the car in the farm yard maybe twice or more during the early season and perhaps a time or two more driving out of the valley coming home. I’ve never been unhappy to see a heavy CO presence during the deer season but now they’re a figment of the imagination.
And for a Darwin type of award, we had an idiot in a ladder stand set on private property, with a gun, having only a sticking cap with about half orange on it, right across the property line. Full camo otherwise. He was there every day both weekends and, yes, he got the tip call.
I hunt a scoped in-line muzzy during the regular season but the “300-500 yard” capability you have mentioned isn’t likely where I hunt, nor in most of the wooded areas in the shotgun zone unless a person is on flat land with nothing but air between him and the target and even then he has to have a bullet that will expand properly at those distances and reduced velocity. Most of those scopes are used for long range target shooting unless the shooter is seriously impaired and thinking that he has one up on the deer.
The buck I shot was at about 45 yards broadside, standing, when I shot him. My doe was a downhill shot at about 95 yards, standing broadside. And the third deer was a doe at 165 yards, severely downhill standing broadside. All one shot kills with one drop-on-the-spot. Off-hand. I take no “chance” shots or shots at a moving target. All were relatively open woods shots. All of these shots would be doable with a scoped shotgun save maybe for the long downhill one.
For the most part I feel safe where I hunt in spite of the zoo tactics that come each opening day. Now if multi-shot, full blown rifles were allowed in this zone, maybe not so much for the safety. Based on how many shot up and gut shot dead deer I have found on the property I hunt over the years I’d say that there are plenty of poor shots or chance takers in the field yet and CF rifles would only make things less safe and worse for the same problems.
