H4350 is a very popular extruded (stick) powder known for its consistent performance and versatility. It is part of Hodgdon's Extreme line of propellants, meaning it is formulated to be highly insensitive to changes in temperature. This provides reliable velocities and pressures regardless of extreme hot or cold conditions, which is a major advantage for shooters. The grain size has been shortened to improve metering through powder dispensers. H4350 is an ideal powder for a wide range of cartridges, particularly for the WSM (Winchester Short Magnum) family (.270, 7mm, .30, .325) and is considered a standard for calibers like the .243 Winchester, 6mm Remington, .270 Winchester, and .338 Winchester Magnum. It is a go-to choice for reloaders looking for a dependable and accurate powder for light to moderate-weight magnum bullets.
