Welcome to the boards. Don't confuse real world shooting concepts with airsoft shooting, two completely different ball games. You'd probably be better off buying a decent AEG, instead of trying to be a sniper. Being a great shot means nothing in airsoft, as the ranges are so short, and things like wind can DRASTICALLY change the flight path of a bb. Not to mention a single shot is ineffective, it often takes several rounds, one right after another, for an opponent to call a hit. For instance, a while back I took a shot at someone from pretty far off(with my rather expensive sniper rifle), and managed to hit them. This person stood there, and looked around, then finally saw me. I was watching him, and he knew it, so he called himself out. Had he not spotted me, I'm sure he would have kept on shooting his AEG at people. Had I done the same thing with an AEG, he wouldn't even have had to spot me to call himself out, because I would have a.) kept shooting and b.) he would probably wouldn't wanna get shot anymore.
