RE: Accuracy and shooting tips....
The problem with long range before the basics are covered,it can cause confidence problems and could cause target panick and form flaws.
That is the reason for the short yardage stuff.Kind of like shooting 5 spot to better your 3-d game.It is only 20 yards but it is a game of perfection and REPETITION.
Randy Ulmer is very accomplished and I do agree,once you have the basics covered,long range can be a great help to the short range shooting.
