I've been shooting all my life, it's not that hard. I've never understood the challenge. You got sights, line them up, hold your breath, and squeeze between heartbeats. Do it few times, and you get the hang pretty quick.

All my friends are amazed at my shooting, and I have terrible eyesight. I occasionally will put a round through a previous hole in the target. It's not that hard, I've taught it to lots of people with great results. Even people who think they already know how to shoot have improved. It's shocking how many people don't know to hold their breath while shooting. I think it's because a lot of people start breathing harder when they have a gun in their hand, heartbeat goes up, etc.

Keeping your cool while rounds are coming at you at the same time? That's a bit more challenging. But hitting a static target can be picked up in a single session. You might not make consistent head shots, but body mass shots will be good enough.
