The left forward allows the shooter to respond instantly and smoothly to any target. When the target is to the right, I simply point the left foot that way. Again, instinctive and the barrels thrust toward the target smoothly and quickly. Think of it as as a 5" 38 mount on a destroyer - maximum traverse without reset during the shot. And instant ability to pick up a second target. But I am not really debating this. I know it works.@Red Leg the overall approach sounds good, except the lead with the left?. That’s a fairly “clays centric” process. What happens when you need to shoot hard right? Is the method workable when you need to shift weight and take a shot off the balls of your feet in the opposite direction than intended?
And yes, I spent a lot of time on high pheasant so I am prone to shooting a form that allows a vertical shot, although that’s not needed in most rough shooting. Probably why my form is based on the biased of how I was taught and what I shot most. (Doves and driven) Believe it or not, never killed a woodcock or a quail with a gun before! (But I’m open to invitations!)
I would also suggest, it is the only effective way to hunt pointed birds or driven birds when the guns are part of the drive (wild South Dakota pheasants and European huns spring to mind.)
I have killed tens of thousands of driven pheasant. I find the true vertical shot wasted effort - particularly with an off-foot address. I'll easily kill him a half second earlier to my front. But hey, If it works for you, then great. Shooting style - regardless what instructors believe - is very personal.
