Hodgdon H1000

This very slow-burning Extreme Extruded powder is perfect for highly overbored
magnums like the 7mm Remington Magnum, 7mm STW and the 30-378 Weatherby.
In addition, with heavy bullets, H1000 gives top velocity and performance in such cartridges
as the 6mm-284, 257 Weatherby, 270 Winchester, and 300 Winchester Magnum. In a short
period of time this powder has achieved considerable notoriety among long range match
shooters.
