I realize you are asking a loaded question. There is not a perfect solution. Just merely my opinion, but something like a 4x scope maximum and no exposed turrets or bdc reticles is where I’d start.
I know some will say nothing will stop guys from still slinging lead 800+ yards with a 4x scope but I’m of the belief that most hunters are ethical humans and would keep it reasonable.
Heck, imo even a 3x9 max would probably save some animals. It wasn’t that long ago when that’s about all we had. I know back in those days I wouldn’t even think of taking a 400+ yard shot. Now, I don’t even think twice about such a shot with the gear we have. That’s a chip shot. You can’t tell me that kind of advantage hasn’t punched more tags in recent years.
I’ll do it with a 4x scope and a reticle..
The rangefinder is the biggest single game changer in the last 2 decades in western hunting.
