z1r,
Of course they quit making them--for the moment, which is why they're so scarce. But Nosler doesn't "delist" bullets from their website if they're still planning to make more, and the 250 9.3 AB is still there.
Like any other bullet company, they don't constantly produce all their bullets, all the time, because they don't have a separate machine to make every bullet. They make bullets that are less in demand during slower times of year, when they can take the time to switch out the dies and other equipment. The 9.3 AccuBond isn't in nearly as much demand as, say, 180-grain .30-caliber Ballistic Tips, and neither is the .17 caliber Tipped Varmageddon. But they still make both the 9.3 and .17, when they can.
