Shot a 401/500 1X in the match today, using my 16" AR carbine. I'm rather pleased with that, since I haven't shot positions in months.
As I was shooting, the Appleseed lessons kept ringing in my head. Position, natural point of aim, sight picture, breathing, squeeze, follow through.
Appleseed works, and I mean the shooting lessons. The lessons in history... those find fertile ground as well.
