Burn rate
A slow magnum-class rifle powder, charted just past Alliant Reloder 25 and ahead of Vihtavuori N565 — slightly faster than Accurate MagPro.
Chart agreement: Ranked from Hodgdon's current revision, which charts it between Alliant Reloder 25 and Vihtavuori N565. Not present on the older revision used as this list's spine. Ranked by: Hodgdon.
Powders charted near it — neighbours on the chart are not substitutes, and adjacency tells you nothing about what charge either one takes:
- Vihtavuori N165 (position 173)
- IMR 7828 SSC (position 174)
- Alliant Reloder 25 (position 175)
- Vihtavuori N565 (position 177)
- Vihtavuori N170 (position 178)
- Accurate MAGPRO (position 179)

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.
