Per Winchester.com, WM1931000 is covered.Just a note that is bulk case (not individual boxed) and Winchester says they will not accept case barcodes for their rebate offer.
I expect what they mean, when they say "Case UPC Codes will NOT be accepted," is that if there are individual boxes inside your case, you need to send their UPCs, not that of the outer box.
The other warning we should note is that the rebate is capped at $75. So if one buys this (full price) case for $499.99, they won't get the full 20% back, and will end up paying $424.99. That said, a Prime member, who pays $459.99 will get the same $75 max rebate, bringing it down to $384.99 (plus tax, where applicable).
Still, 38.5¢ per round is not that bad, considering 2 years of shortages and the last year of inflation.
