Description
This is the 24N41 8lb keg from Vihtavuori, a slow-burning, double-base rifle powder designed for heavy magnum cartridges. It’s for the handloader pushing big bullets at high velocity who demands consistency. Since we put it on our shelves in spring 2025, we’ve seen a low return rate—folks know what they’re getting and it delivers.
What Makes It Stand Out
- Proven Reliability: Our range officer tested this against three competitor powders in .338 Lapua loads. This one won on reliability, with no pressure spikes and consistent velocities.
- Exceptional Lot-to-Lot Consistency: Vihtavuori’s manufacturing process is tight. You can trust your developed load to perform the same from one 8lb keg to the next.
- Clean-Burning Formula: Leaves minimal residue, which means less time scrubbing and more time shooting. Your barrel stays cooler and fouling is manageable.
- Temperature Stable: Performance holds up in both summer heat and winter cold, so your zero stays true when it counts.
- High Energy Density: You get serious velocity potential for large magnum cases like .338 Lapua, .300 Norma Mag, and .408 CheyTac without maxing out your case capacity.

Common Questions
Is this suitable for .50 BMG loads?
Yes, absolutely. 24N41 is one of the go-to powders for .50 BMG reloading. It provides excellent velocity and consistent burn in the large case volume. Always start with published minimum loads and work up.
How does it meter through a powder measure?
It meters very well. The spherical granule shape allows it to flow smoothly and consistently through most powder measures, giving you precise throws for each charge.
What’s the shelf life like?
Stored properly in a cool, dry place with the lid sealed, this powder will last for decades. Vihtavuori powders are known for their long-term stability. We’ve never had a customer report an issue with age.
