This last weekend I had the opportunity to shoot with Jamison Yoder of TPArms. I would recommend any of his courses to beginners or the experienced shooter! He's an extremely nice guy and has experience as an X sniper so he knows what he's talking about. He also builds custom rifles that consistently shoot one hole. I plan on having him build me a rifle! Check them out, nothing but good things to say about them!
