From what I remember they didn't specify make...and I've never actually seen any .22g bb's...anywhere. I've no idea why they wouldn't use the standard .20g unless it provided numbers that were not what supported their theories. While WA does have .22...they are not common ( as i've said..I've never seen .22g bb's before ) back in the day when the test were done ( 98-99?) I don't see them as being popular either.
