Vihtavuori N500 High Energy

Vihtavuori N565

A newer powder developed for the .338 Lapua Magnum and adopted for military sniping, long-range precision and ELR competition.

Developed for the .338 Lapua Magnum and adopted hard by military sniping, long-range precision and ELR shooters. It was deliberately placed to split the gap between N560 and N570, which tells you it was made to solve a specific problem in big magnum cases rather than to be versatile. The claim set is the strongest in the line, with extreme temperature stability, improved humidity stability and a decoppering agent, and this is the class of shooting where those claims actually get tested.

Grain shape

Single-perforated extruded grains the same physical size as N560, so the surface treatment does the burn-rate work here rather than the web. Neutral-burning tube, which is what keeps pressure controlled in a case holding this much powder.

Why geometry decides burn rate more than chemistry does: Shape Is the Product.

Single-perforated extruded grains, same physical size as N560. Vihtavuori states it is extremely temperature stable, has improved hygroscopic stability, and carries a decoppering agent; they also describe it as REACH compliant without DNT or phthalates.

Burn rate

Deliberately placed between N560 and N570, splitting the gap between them.
