Pugsley, I can vouch for the quality of today's bio bb's. I've shot bastards and biovals against a concrete wall with little breakage, which you'd better expect when shooting 60 feet into a concrete wall :P
10 years ago (heck maybe even 5 years ago) bios did suck donkey nuts... but look at it this way, with the quality bb's that bb basterd provides, and the popularity of those bb's with players, why would he offer a bio bb if it wasn't up to the standard of the rest of his line?
