Help on learning about firearms: I live in Poteau, OK, and I would like to learn how to properly shoot and use my scope settings. For long distance target shooting. I have a Winchester model 70, 223 and a Ruger Mark M77 Mark11 7 mm mag. My scopes are a Zeiss 3-9x44 and a Burris 3-9 fullfield soon to be upgraded to a Zeiss 6.5-20x50. I just need some education on how and what to do to get started.
