next pay day i'll be buying more magazines from amazon with .20 and .12 bb's,
NO NO NO NO NO NO NO NO NO NO NO NO NO. If you plan on having this gun for a while, treat it with a little respect. Putting .12g bbs in it will forget up the inner barrel. It will scratch it to stuff. Even risky going with .20g bbs.
If you want my input, go for .23 or .25 Goldenball/elite force/bb bastard Seamless, double polished, with accuracy to .01 BBs. Never buy Crossman brand BB's, anything thats clear/.12 or anything cheap for any reason what so ever.
