Will BBs from Sports Authority damage my Airsoft Gun?

I have a clic army SCAR light airsoft gun, It is a full metal replica that shoots 330 feet per second, it was $360.00 and i am very proud to own such a high cl airsoft gun. I understand that BBs such as Crossman and other low cl BBs can strip a high cl AEGs gearbox, however i have recently purchased Billies Biodegradeable BBs from Sport Authority and i was wondering if they would strip my gearbox or cause any other type of damage to my gun. They have no seam lines and look and shoot in my low cl guns like good high cl BBs. Will these harm my precious SCAR?
