Understanding 4451 with ENDURON Technology

As an extruded powder, 4451 has consistent burn characteristics from its spherical pellet morphology. Its moderate-fast burn rate produces effective pressures in calibers from .223 Rem to larger. ENDURON Technology further enhances 4451’s consistent burn for less velocity/pressure deviation between shots. This helps minimize fouling.

Reloading with 4451

When reloading, carefully select bullets, brass, and primers as specified in manuals. Weigh charges on an accurate scale within published data ranges. Ensure consistent seating by sizing brass, seating bullets to proper COL, and crimping. Document top loads for precision applications.

4451 is well-suited for cartridges loaded with 55-150 grain bullets, generating velocities for informal/long range shooting, plinking, and hunting. Excellent options include .223 Rem, .308 Win, 6.5 CM, 30-06 Sprg.

Safety Considerations

Always follow safe handling and reloading procedures. Store 4451 in a cool, dry place away from heat sources. Regularly inspect powder levels and rounds. Wear protective equipment while reloading and shooting. Never exceed max published loads.
