Don't worry about being a noob,we'll help you out. For the MOA adjustments, basically you'll want to use a ballistic calculator to create a drop chart/range card. That will tell you what adjustments to dial in for the specific range of the target, or for the wind conditions. I use JBM ballistics. www.jbmballistics.com You'll need some basic data to use it. Muzzle velocity (or at least a best guess), bullet type (ie sierra 175 SMK), and the height of the center of your scope above the bore axis. Plug these into the webpage and you can create a chart based upon a 100 yard zero. There is also an option for you to plug in the specific ranges of targets. I'd do both, one as a generic range card and one for Thunder Valley. Target ranges are Position 1 223 390 550 348 Position 2 280 420 365 550 Position 3 170 280 500 475
