I’m also going to be a bit contrary to what others have said about shotgunning and rifle shooting. It could be that those who’ve dedicated themselves to both disciplines are good at both and that’s how it works out. On the other hand, one’s focus is so different in the act of making the shot that I don’t see how one helps the other. The only thing in common is that the gun is in motion while the shot is taken. With a shotgun, if you look at the bead you’ll miss the shot 9 out of 10 times. Yours focus needs to be on the target. I think the opposite is true with a rifle. Focus on the front sight or reticle or all is lost.
