RE: scope question?
Yep, if you know what you are doing and know your rifle, if you can see it, you can hit it. And the only thing parallax correction does is make up for poor form. If you align yourself perfectly with the scope for every shot you really don't need it. Especially on game where you have may have inches of error built into the shot. They are nice for target shooting though where you need absolute precision.
I tend to use AO scopes if I get more power, just because I like them, sort of like your turrets. And I really like mildot reticles. I'm sort of the opposite of you I guess. I would rather hold over than dial it into the scope. Don't know why to be honest. Once I get my scope sighted in I prefer to just not touch it again. Probably comes from using really cheap scopes when I was younger.
Nice shot by the way.
