I just got a new scope and it has about 50 MOA of adjustment, not much really. I'm using it on a 308 BAR that is very accurate, with the last scope. Today I mounted the scope and it is almost against the rail. The rail is -0- MOA. I had to crank the elevation up all the way and was still 2 inches low at 100 yards. WTF, I guess I don't understand the scopes bore line and the guns bore line correctly. What should I do now? Mabe someone can explain this to me. Almost all of my rifles have a 20 MOA and scopes, 50 or more MOA. I guess I haven't shot long enough to have had to dial all the way up? I'm out of elevation and 2 inches low at 100. Should I be shooting backwords!? lol Please explain. Maybe the dial on my scopes is backwards? haha HELP.
