Burn rate
The fastest-burning powder Vihtavuori makes, and the first entry on their own burn rate chart.
Chart agreement: consistent - ranked at or near the very fastest position by every publisher that lists it. Ranked by: Hodgdon, Vihtavuori, Shooters World, Wolfe/LoadData.
Powders charted near it — neighbours on the chart are not substitutes, and adjacency tells you nothing about what charge either one takes:
- Alliant Extra-Lite (position 4)
- Shooters World Sparta 100 (position 5)
- Accurate Nitro 100 NF (position 6)

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.
