I use to do the 3-D when i was able. The main thing is mentally marking your distance on each shot. Walk up to any 3-D targets prior to the starting the shoot get good looks at those 12 and 10 rings yer shooting at. They did tell regular sights no scopes? Yer foot don't matter which one has to touch stake as you shoot. They will talk trash to you while yer trying to shoot so as to mess you up. We had targets from 5 yds. to 50 yds. I would attend them here cept gas prices have put hurt on anything extra not in budget. Best of luck to you and show them were just like them!
