Re: targets
The first sticky post in the thread has a collection of free printable targets by StormfTactical. There are a large selection of MOA and Mil targets. They are great for setting zero, and checking scope tracking of your reticle and drills. Download them all, print the ones you want and go to kinkos. As for Opsgear, forget all that zombie crap, get your fundamentals down first, this means knowing your scope, knowing your dope.
Have fun
