My whole goal in all of this is when my kids start hunting on their own I can sit at the Cabin and drink beer and run the BBQ pit all the while watching the lower wheat field. If a big one walks out I just wanna be able to make the shot with minimal correction. I have the mark AR leupold scope so I guess I could just get leupold to build a knob to fit my load and then dial it in. Yep I'm getting lazy and old! LOL!
