Yes and No. If you bought those eco BBs from a sports store like sports authority, then the bbs cannot handle the pressure of your gun. It will shatter in the inner barrel and cause massive jammings. If you bought those bbs from a reputable airsoft store such as airsoftpost or airsoftgi, then the performance will not change. Anyways, you shouldn't be playing at your house, you should be playing at a licensed airsoft arena.
