Supreme 780.jpgNew Supreme 780 Winchester Smokeless powder is the same powder loaded in Winchester’s factory Supreme ammunition, including .243 Win., .270 Win. and .300 Win. Mag. rounds.

Supreme 780 is a Ball Powder propellant, which means easy measure flow resulting in consistent charge weights. Comparable in burn speed to H4831, it fills a niche that previously was not available in Winchester Smokeless offerings. Researchers have developed data for 14 cartridges and more than 35 recipes.

One- and 8-pound containers will be available in Spring 2008.
