How Winchester ever managed to stuff that 1 5/8 oz Lead load into 2 3/4" inch shell is beyond me and I always figured they told a fib and just repacked the 12 gauge 2 3/4" inch 1 1/2 oz Magnum load into that box like they did for the 10 pack Super-X Turkey loads that are actually the same shell as the Supreme XX Magnum 25 count boxes...........same exact load and shell by the way......just they sell them cheaper in the Super-X 10 pack to make you buy the more expensive 10 pack Supreme HV 3" inch 1 3/4 oz High Velocity stuff that was called new in 2004
