Description
IMR 4198 is a versatile, extruded rifle powder designed for consistent performance in a wide range of cartridges. This 8-pound jug is for the serious reloader who values economy and a proven track record. It’s particularly effective in smaller capacity rifle cases and reduced loads for larger ones. Since we started stocking it in mid-2024, it’s become one of our steady sellers for good reason.
What Makes It Stand Out
- Extruded Kernel Design: Meters consistently through powder measures for reliable charge weights.
- Broad Application Range: Works well in cartridges from .223 Remington up to .458 Winchester Magnum with reduced loads.
- Temperature Stability: IMR’s formulation provides reliable performance across varying conditions.
- Clean-Burning: Produces minimal residue, leading to easier firearm maintenance.
- Shop Proven: This is the model we personally use in our shop demo Glock. Says enough.

Common Questions
Is IMR 4198 suitable for .223/5.56 reloading?
Yes, it is an excellent and popular choice for .223 Remington and 5.56 NATO loads, especially with lighter bullets (40-55 grain). Always consult published load data.
How does it meter in a powder thrower?
Very well. The extruded kernel shape allows it to flow smoothly and consistently through most powder measures, giving you uniform charges.
Can I use this for 300 Blackout subsonic loads?
It can be used for some subsonic applications, but it is generally better suited for supersonic 300 Blackout loads. Always cross-reference with current, reliable load data for your specific bullet.
