References for 20mm, 25mm and 30mm ammo?

Can anyone provide some good reference materials on subject ammo (primarily US types)? I have a request from someone who will be doing range clearance ops seeking unclassified reference material, either on line, paper or digital.


I have a pdf file of the “US Army Ammunition Data Sheets, Small Calibre Ammunition FSC 1305” dated April 1994, which covers everything up to 30x113B. If you give me your email address I’ll send it to you.
