Vihtavuori N105 Super Magnum

Intended for the most powerful handgun cartridges in current use, especially those with heavy bullets or large case volume; Vihtavuori notes several of these rounds operate at rifle pressure levels.

Vihtavuori's magnum handgun powder, for the cartridges that are really short rifles: .454 Casull, .460 and .500 S&W, heavy .44 Magnum and full-power 10mm. It fills those big cases well, which is exactly what you want when the alternative is a small charge of a fast powder rattling around in a lot of empty space. Like the ball magnum powders it wants a full-power load and a firm crimp; it is not a powder for downloading.

Grain shape

Extruded tube, neutral-burning: surface stays roughly constant as the perforation opens, so the pressure curve stays civil in a case that is running at rifle pressure. The grains are small enough to meter acceptably, far better than any rifle stick.

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

Despite the N100-style number, Vihtavuori groups N105 with the N300 handgun and shotgun powders rather than with the N100 rifle series. It does not appear on their published canister burn rate chart, and no standalone product page exists on the current site.

Burn rate

Vihtavuori's slowest-burning handgun powder.

Chart agreement: coverage gap in the opposite direction - ranked by Hodgdon and Wolfe/LoadData but omitted from Vihtavuori's own current tabloid chart. Ranked by: Hodgdon, Wolfe/LoadData.

The two “RCM's read” sections are ours, not theirs — our assessment of what this powder is like to load, drawn from its published characteristics and from what handloaders consistently report. No manufacturer endorses them and no source below backs them. If you think we have one wrong, tell us — we would rather fix it.
