Hey guys and gals just wondering if someone can help me make some sense of a couple of terms I see being used a lot on here. Node, as in finding the node? SD, I've seen used with along with ES (extreme spread I get)? Killing critters at 1300+ yards??? Please help me with this one especially!!! I love this site and spend way to much time on here but can't get enough. I'm thirsty for knowlege and you guys are great teachers!
