2 mags is plenty, one in the gun while one is being reloaded.
" If you're not hitting your target with the first or second shot, get closer or wait til they come to you. The more plastic flies, the faster they ID your position."
I compleatly disagree with that statement in regards to airsoft play.
AS "snipers" just don't have the stand off distance compared to RS, if you are close enuft to garentee a hit, they are close enuf to dump a hicap in to your position and let the law of advarges take over.
for the most part players won't notice "misses" @ 200+, even if they do they have no idea were it is coming from, I have whacked whole squads who chose to take cover facing the wrong way.
the best way to learn is to shoot, the best way to profesant @ shooting in field conditions (as apposed to range) is to shoot in them.
the best way to keep AEGs away from you is to remove the threat before they can hose you, doing this means endgageing them beyond your "effctice range"... witch is more dependent on the shooter then the equipment
to hit @ long range you need to shoot @ long range.
pull the trigger, track the bb in the scope, adjust the point of aim, shoot again. its the only way you are going to learn range estmation and correction.
rember Furlong missed his first 2 shots before the 3rd set a record
