Alright. I was worried, because I can't imagine a worse feeling in airsoft than to have the first shot fired from a brand new gun set you back a little bit. Goldenball seems like a really nice brand, I might see what I can do about getting myself some of those.
Derp, how could I forget the weight? Thanks for the reminder, I'll probably buy some .3s soon.
On the topic of weight, if this gun fires at a theoretically consistent 420 fps, then what is the highest and/or lowest functional BB weight I could use?
