And yet Ben, due to something called parallax, target speed has the least impact on a successful shot and in any case, by seeing lead at the muzzle target speed is completely INCONSEQUENTIAL on ALL the angular shots. Angle and perceived lead is what matters. And BTW every target (In the area you intend to shoot it) is either rising or falling. it is a narrow angle, intermediate angle wide angle or full crosser. Just like it was 200 years ago.
And BTW here is something that expect you will find very interesting. For those over there that have my book Successful Shotgunning on page 206 I say "on page 50 in the December issue of Sporting Clays magazine there is an article by Nick Siseley, Stellar Star of the game about Jon Kruger who at that time was the US Champion". Quote from the article "You've heard the axiom over and over, look at the target, look at the target. Surprisingly, this isn't what Kruger does. Instead he tries to look at a spot in front of the target. Why? Because that's where his shot needs to go."
In other words EXACTLY what Richard Faulds says he does and ALL my clients and many of the Masterclass and World Champions have found out. And IF THEY KNOW THE LEAD it is very, very easy to do.
But when I first came here to the US, some coaches were preaching the familiar "Focus on the target so intently that you can see the rings on the top, direction of spin etc" and "The magic of your subconscious will tell you where to put the gun." They said that because most of them could not explain lead in a logical way. These same coaches would then tell you "You gun should shoot where you look." So, if your gun "shoots where you look" and you are still focused on the target on a 40 yard crossing shot, won't your shot column go 10 feet behind the target? Of course it will. But the look in front is only for the smallest fraction of time 1/50 th of a second, and only when your target reading skills is up to standard.
