40 S&W and Alliant Herco

This is not pertaining to savage's or rifles. But I have searched for a hour on line and cant seem to find any data on it. I have 2lbs of Herco that were almost free and now i know why! Haha because there is hardly any data out there! anyways i was wondering if anyone else knew anything about Herco powder and 155 gr Berrys plated. I would love to use some of it up.

Also if this gets moved, I understand. I appreciate this site and chose to post it here. I would rather ask my friends and people i know (this site) rather than jump in a strangers house (a different site, more suited to this question) and ask them.
Thanks!
Henry.

Correction, one can is new, Alliant-Herco. One can is old, but still good. Hercules-Herco. Im sure that Alliant bought out Hercules? anyways just wanted to give you that info.
