Product Overview and Introduction

Unlock exceptional accuracy, reliable ignition, and absolute temperature stability with Hodgdon H4198 Smokeless Gun Powder. As a cornerstone member of Hodgdon’s renowned EXTREME FAMILY of propellants, H4198 has been meticulously engineered to resist velocity shifts caused by ambient weather changes. Whether you are shooting in freezing winter hunts or high-heat summer target matches, your handloads will maintain consistent velocities and pinpoint accuracy.

Featuring short-cut extruded kernels designed to meter exceptionally well for an extruded powder, H4198 is a legendary performer in small-capacity rifle cartridges like the .222 Remington and 7.62x39mm, as well as straight-wall and traditional big-bore favorites like the .45-70 Government and .444 Marlin.

Extreme Temperature-Independent Extruded Technology

Engineered to meet the stringent demands of precision shooters and heritage cartridge handloaders, H4198 offers advanced ballistic performance:

• Extreme Temperature Insensitivity: Specially formulated chemical additives eliminate velocity swings across drastic hot and cold weather shifts.

• Short-Cut Extruded Kernels: Manufactured with shortened propellant grains that settle smoothly and measure more uniformly through volumetric powder measures.

• Optimized for Small-to-Moderate Bores: Ideal burn rate for rapid, complete combustion in cases with restricted capacity, preventing unburnt powder and erratic pressure curves.

• Versatile Big-Bore Performance: Trusted globally by casters and reloaders for powering classic lever-action and single-shot rifle cartridges with heavy lead or jacketed projectiles.

The Professional Choice for Precision and Heritage Reloading

When your reloading bench requires a versatile, temperature-stable extruded powder that excels in both small-capacity bottleneck cartridges and hard-hitting traditional big-bores, Hodgdon H4198 stands out as an irreplaceable classic.
