Best bet would be to come out to a game. Outdoors you'll have a lot of range to use
We have a game comming up on the 22nd at finch field airsoft I'm sure myself or one of the other vets would be glad to help you out with dialing in your hop up for greatest effective range.
check out finch field airsoft on facebook or brows the games listing here (if you can do that without AV status.
Welcome to airsoft and welcome to ASC!
