Ive been only playing airsoft for a little while cause i didnt know any better i went to walmart and purchased 10000 black ops .20 gram bbs. Now the black ops perform ok but after some research i think its time to move on to .25 or .28 bbs. Ive played with elite force .25 bbs and my only complaint with them was the price. I hear TSD and Golden ball are good brands and ive seen them go for about $35 on ebay for 10000 .25. Has anyone had any experience with buying bbs off Ebay? Also id like to know where you buy your bbs how many you get what weight and the price. Do you buy local or do you think it better to purchase bbs online?
