I just noticed that this 1960 issue of Guns Magazine is now available for free online.  It features legendary shooter, Lucky McDaniel, who was famous for teaching and exhibiting instinctive shooting.  Lucky’s method formed a good basis for a lot of what our instructor, Buz Fawcett teaches about instinctive shotgunning.  It’s a good read, here is the link to the magazine:
