All the game folks would have to do is to put a range limitation on these, e.g., no more than 800 yards, to limit the distance. Manufacturers would comply. Given separate laser rangefinders that will range beyond 1000 yards and provide quick mil comeups are available, all the bans do is make things take a few seconds longer. In short, they're silly.
Re harvests, game depts do annual game counts and they survey hunters. They can limit tags to limit harvests. I think here in WA the hunter success rate is well under 20% for deer and elk, and it's not from overhunting but from range destruction... the windmill farms throughout the Kittitas valley aren't elk friendly. The areas I used to hunt in the late 80s now have more orange-clad hunters than deer. With the prohibitions on hound hunting we have lots of cougars and wolves (including on the west side of the Cascades), and very few deer and elk compared to the 99s and earlier.
The reason hunters take longer shots is because often that's all that you get. Why not let them have equipment that still requires good marksmanship but lessens the chances of wounding?
