Federal XM193 two types????

My distributor has XM193 and XM193C
Federal told me that the differenc eis the way they are packed but wouldnt tell me what the difference is or which one is which.

Can anyone tell me how each is packed?

Federal did say that the stuff was all Lake City and it didnt meet MILSPEC and they also specifically stated that it didnt meet waterproofing standard.

XM193C is packed in 20 round boxes. I believe that XM193C is what used to be designated simply as XM193.

There is also an XM193A on the market that is on stripper clips.

I just bought 260 rounds of this:
