C-pher,
I AM going to "answer that"! . . . OK dumb-ass!
http://www.ups.com/content/us/en/resources/service/tariff.html?WT.svl=SubNav Should give you a downloadable "tariff" pdf file to search thru.
Because we aren't sure you know how to use the Search feature yet . . .
Section 425, pg 5 of the pdf file (pg 4 of the actual document), towards the bottom of the page!
Section 458, pg 9 of the pdf file (pg 8 of the actual document), towards the bottom of the page!
ORM-D information:
Section 580, pg 22 of the pdf file (pg 21 of the actual document), at the bottom of the page! This info continues on the following page.
ORM-D weight restrictions can be found on pg 30 of the pdf file (pg 29 of the actual document), at the top of the page!
I do NOT believe that UPS gives/sells ORM-D stickers to customers. They are a DOT/DHS requirement and are available thru label companies, perhaps the large box office supply places may sell them, you can use a previously used ORM-D marked box, or you might get away with hand lettering it carefully in the same format that DOT/DHS allows.
The most useful info that Google could find on how to mark ORM-D on a package is on the Fed-Ex rules website. Look here and search for ORM-D.

Reading FedEx's latest tariff, they will (supposedly) ship ammo via FedEx Ground. I'll leave it to the reader as an exercise to read and find it in their tariff. Hint: The tariff is also downloadable from their Support site.
