Personally I use 5 pins. 20, 30, 40, 50 and 60 yards. While it is very unlikely that I would ever shoot at a game animal over 40 yards I find that practiceing at 50 and 60 yards makes shooting at the closer ranges much easier. Once you get to the point of shooting nice groups at long range it will seem as if the short shots are gimme' s. I use .019 diameter pins so they really don' t appear to be to close together. Just my .02 cents worth.
