Hodgdon H4198 Smokeless Gun Powder

Clear Product Overview

Hodgdon H4198 Smokeless Gun Powder is an exceptionally reliable, fast-burning extruded rifle propellant. Manufacturer Hodgdon Powder Company engineered it to deliver match-grade accuracy, high thermal stability, and clean combustion in small-capacity rifle cases and heavy straight-wall cartridges.

First, as an essential member of Hodgdon’s famed Extreme Series line, H4198 is chemically treated to resist ambient temperature variations. Consequently, it maintains consistent chamber pressures and velocities whether shooting in freezing winter hunts or scorching summer benchrest matches. In addition, its fast burn rate makes it a premier choice for cartridges like .222 Remington, .223 Remington with light bullets, .45-70 Government, .444 Marlin, and .7.62x39mm. Furthermore, its short extruded stick grains flow smoothly through volumetric powder measures. Therefore, it delivers tight group consistency and flat trajectories across both varmint and big-bore lever-action rifles.

Real-World Use Information

Handloaders select Hodgdon H4198 because it combines fast-burning efficiency with Extreme Series thermal stability. Consequently, long-range varmint hunters and benchrest competitors can depend on exact point-of-impact stability across changing weather conditions.

Additionally, its performance in heavy lever-gun rounds like .45-70 Government makes it a top choice for modern hunters seeking clean, efficient burns at both standard and elevated pressures. Furthermore, its short-cut stick geometry drops uniformly through rotary powder measures, saving time during high-volume precision loading.

Compatibility & Requirements

• Application Use: Performs best in small bottleneck rifle cartridges firing lightweight projectiles and large straight-wall cases.

• Load Data: Always consult official Hodgdon reloading data manuals before charging cartridge brass.

• Storage: Keep this powder in its original sealed container in a cool, dry area away from direct heat sources.

Pros & Limitations

Pros:

• Extreme Temperature Stability: Resists velocity fluctuations caused by extreme hot or cold weather.

• Varmint & Lever-Gun Versatility: Benchmark performance from .222 Remington up to heavy .45-70 Government loads.

• Clean Burning: Advanced grain structure leaves minimal carbon buildup in barrels and gas systems.

• Uniform Grain Size: Short stick kernels meter smoothly on standard reloading equipment.

Limitations:

• Not For Standard Medium Cases: Burn rate is far too fast for mid-to-large capacity cases like .308 Win, .30-06, or magnums.

• Not Interchanged with IMR 4198: Load data for Hodgdon H4198 and IMR 4198 differs slightly and must not be swapped without checking manuals.

Frequently Asked Questions (FAQs)

Q: What is the difference between Hodgdon H4198 and IMR 4198?

A: While both share a similar burn rate, H4198 is part of Hodgdon’s Extreme Series (offering enhanced temperature stability) and is manufactured in Australia, whereas IMR 4198 is made in Canada; their load data is not directly interchangeable.

Q: Is Hodgdon H4198 good for .45-70 Government reloading?

A: Yes! Hodgdon H4198 is one of the most widely recommended powders for .45-70 Government, producing high velocity and clean combustion across various bullet weights.

Q: Does Hodgdon H4198 meter well in powder measures?

A: Yes. Because it features short-cut stick grains, H4198 meters much more smoothly than older, long-cut extruded powders.
