I went out to the range today with my M39 (open sights) and set up 5 sporting clays on the 225 yard birm. I gave myself 5 shots per clay and I would move onto the next one. I busted 4 of em, (2 of them on the second shot, 1 on the third, and one on the 4th) but I just couldn't hit the target in the middle.
At 225 yards though, I can keel some zombies
