'Cartridges of the World' is a DBI? publication.
Updated every few years I think.
They have a chapter that shows current - as well as past - specs and weight tolerances of components used in addition to powder type and charge weight for all military cartridges 9mm thru 30mm.
Chronographed velocities are also shown.
That chapter, of course, includes the crimped primer 855s.
