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.

- Alliant 2400 (position 63)
- Ramshot Enforcer (position 64)
- Accurate No. 9 (position 66)
- Accurate 4100 (position 67)

Verify the charge, not just the recipe
Good data gets you a safe starting point. It does not tell you what actually went into the case on stroke 340 — a bridged measure, a double charge, a squib. That is what an RCM Laser Powder Check is for.
