bb's

My bro and I were talking about BBs this afternoon, and I mentioned how Biodegradable bbs are better to use. He then counters, telling me that bio bbs are more fragile, and that they will break against mesh masks.
Do you think this type Bio bb's are fragile too?

If they break on mesh goggs I wouldn't worry mate! it's quicker for the bb to disintergrate into the environment. Plus, at least you know you've been hit the face too!

If they shatter on impact expect a random chrono check

I have been playing airsoft for years and hit in the face 100s of times and never had a problam with mess goggles , yes bbs do shatter but only when using high fps and cheap bbs.
