Interesting.
Winchester went from 333 to 555 rounds in THEIR bulk pack, and Federal went the other way, 550 to 375. Different focus groups, obviously.
The cynical side of me says they are changing to these oddball numbers in their bulk packs only to disguise price increases. I can't believe ANYONE thinks 555 or 375 is a nice easy-to-remember round number, but it does conceal an increase from about .333 cents a round to .34-something quite well.
