Remington still list them on their web site. But I'm going to stop by the gun shop today and buy 3 or 4 more boxes, that should last till I die since I only need one per year.

A close examination of the big game record books quickly reveals one strikingly consistent fact; the overwhelming majority of trophy book whitetails are found in slug-only states. Why stake your hunt on inferior shotgun slugs? When the buck of a lifetime steps out at 150 yards, go ahead and squeeze the trigger!
When it comes to delivering devastating knockdown power and superior accuracy, no other lead slug offers a more lethal combination than the Remington BuckHammer. Specifically designed for rifled barrels and rifled choke tubes, these high-performance slugs are capable of producing 3-inch or better groups at 100-yards with nearly 100% weight retention and controlled expansion to nearly one-inch in diameter.
Unlike traditional sabot slugs, the BuckHammer’s unique attached stabilizer allows for a full bore diameter lead slug that delivers devastating terminal performance with unsurpassed accuracy. Now available in 2 3/4-inch and 3-inch magnum loads in both 12- and 20-gauge the awe-inspiring BuckHammer is the hardest hitting, most accurate, highest energy family of lead slugs available.
