my gun was originally shooting 368 and now its shooting 398 and all that happened was the spring was put in wrong the first time. ive always just rolled with it and i havent really noticed any difference other than faster bbs. im debating downgrading actually so i can play cqb with it. anythign around 330-390 is optimal for me lol i used to only use semi auto but then it broke
lol i really need to get that fixed
