Mack,

Great photos! Thanks for sharing. Did you pick that ammo up just recently? If you did, may I ask where?

I'm just wondering what's so special about this XM10 ammo for Federal to print "10mm AUTO SPL" on the box label. Possibly a reduced velocity loading. Any ideas?

Federal uses the "XM" prefix on their product numbers for limited run or special orders. These XM products can be made for LEAs here in the states or for agencies outside the U.S. Federal will put these products out for sale on the civilian market when they have an over-run of product, if the product is rejected by the end-user or if they screwed up something at the factory which doesn't meet the end-user's criteria.

A few years back Federal sold off a whole bunch of 9mm that was made for the Taiwanese National Police. It was rejected because it didn't meet their criteria for water-proofing.
