Winchester Super-X 22 long rifle box of 250

Can anyone tell me when Winchester produced Super-X .22 long rifle rim fire 40 grain Lubaloy (product code 22LRBP) in a 250 round box? It has been zillion years give or take a few since I have bought ‘new’ ammo for shooting purposes, so I haven’t kept up with packaging trends. I know they produced .22 WRF in a 250 round box, but have been unable to find information on a .22 LR box of 250. I just bought several boxes which I have not received yet, and can only assume these are ‘bulk pack’ boxes with the cartridges loose in the box.
