Hodgdon's will be distributing this. Here is a press release on the new Win. powder. I try to keep you guys well informed, eh! WINCHESTER® SMOKELESS PROPELLANT “For Loading Professionals” Tim Vaitekunas Director of Marketing and R&D today announced a potent new addition to the Winchester Smokeless line called Supreme 780™. Supreme 780 is the same powder loaded in Winchester’s factory Supreme® ammunition including 243 Win., 270 Win., and 300 Win. Mag. “This propellant allows the handloader to duplicate Winchester Supreme factory loads,” said Tim discussing this product. “Our state-of-art ballistics laboratory has initially developed data for 14 different cartridges with over 35 different recipes”. Supreme 780 is a Ball Powder® propellant, which means easy measure flow resulting in the most consistent charge weights. Comparable in burn speed to H4831®, it fills a spot that previously was not available in Winchester Smokeless offerings. One and eight pound containers will be available at dealers Spring 2008. Supreme 780 reloads are now on-line at wwpowder.com in the Reloading Data Center.
