Vihtavuori N133 Powder 8 lb Canister

Vihtavuori N133 Rifle Powder - 8lb

Originally developed for the 5.56 NATO cartridge, Vihtavuori N133 has become a favorite among precision shooters and competitive handloaders alike. Tailored for centerfire .22 calibers and PPC cartridges, N133 delivers the consistency and accuracy demanded by elite marksmen.

This tubular powder features 1.1 mm long grains with a 0.8 mm diameter, ensuring smooth flow and precise metering. With a medium burn rate on Vihtavuori’s scale, N133 is a perfect match for .223 Remington—making it a top pick for practical shooters and AR-15 enthusiasts.

N133 also dominates the benchrest scene, especially in 6 PPC setups. Paired with Lapua .220 Russian brass, it's the go-to load for 100- and 200-meter benchrest competitions.
