Im pretty new to this scattergun thing, but when Ive 'seen' my miss it has always been behind. If I shoot where the critter is it aint there once the shot gets there (revelation), I gotta swing through and keep going until I aint pointed at it at all (hard for a deliberate rifle shooter to do!) and put the charge where the critter is going to 'run into it' when it gets there.
How much lead?,,,,,,,,well, how much does the quarterback lead the receiver on a pass?
Im pretty bad but workin' at at.
BTW, the best advice I had early on was when my friend said, " why did you stop swinging when you pulled the trigger?"
