Are these the same thing? I couldn't find anything on "RXM556T3" by search, and Federal's LE web sight doesn't seem to list either load.

Interested in this as well. I have seen this in stock lately but can't find details on it.
Try contacting Federal's customer service and asking. They should be able to find out for you.
I was wondering about this, too. Subscribed...
Same thing. The R means a lot that did not meet the contract specifications and was rejected--this does not mean it is "bad" or substandard...
Thanks Doc for clarifying... as an expansion of the topic, where would one find official/company info on ammo like these? On WINCHESTER'S website, you have to be a hound and search out the 2013 catalog to even know of the existence of RA556B. As for FEDERAL, I go to le.atk.com, their official LE website, and you would never know of XM556FBIT3, MK318Mod0, or even that they make any 5.56 pressure loads at all. If it weren't for websites like m4carbine.net, no one would even know of their existence at all... I figure that WINCHESTER'S is just poorly designed or poorly updated... FEDERAL'S on the other hand appears to withold info... Is there another official FEDERAL website for these full power 5.56loads? i.e. MILITARY.ATK.COM?
Thanks again.
