So I think I'd like to try my hand at learning how to shoot out to decent distances which for me will mean 400-500 yards. I am not a hunter and have very little experience shooting scoped rifles beyond 100 yards. At least for the time being I think perhaps a Remington 700 or Savage model 10 in .308 are my most likely choices. My plan is to go Leupold on the glass (like to keep my money relatively local) and probably spend $300-400. While I continue to save up for this purchase I've been trying to learn a bit about scopes, mils, distance estimation, holds, etc. I have been watching the Magpul Precision Rifle DVD and am finding that I am lost when they start talking about holds and wind corrections. They are lucky in that they have a PDA that is doing the calculations but I doubt I'd ever have a PDA to do this for me. Are there any good books or websights to go to in order to get up to speed on the academics so that when I actually do get to go shoot I won't be wasting a ton of ammo just to prove I have no idea of what I am doing? Thanks.
