Hodgdon H4895

Hodgdon H4955 is a slow-burning extruded rifle powder designed for high-performance cartridges that use heavier bullets and benefit from a progressive pressure curve. It is part of Hodgdon’s Extreme line, meaning it is generally valued for stable performance across temperature changes, which can be important for hunting and long-range shooting in varying weather conditions. H4955 is commonly associated with large-capacity, overbore cartridges where consistent velocity and manageable pressure behavior are priorities.

Reloaders often choose H4955 for cartridges such as the .300 Winchester Magnum, .300 WSM, .270 Winchester, 7mm Remington Magnum, and similar high-energy rifle rounds, depending on published load data and bullet weight. Its slower burn rate can help maximize performance in longer barrels and may produce excellent velocity with heavy-for-caliber projectiles. Because it is an extruded “stick” powder, it typically meters reasonably well, though it may not flow as smoothly as fine spherical powders in some powder measures.
