Burn rate
A slow handgun powder, charted between Alliant 410 and Alliant 2400.
Chart agreement: consistent, but single-publisher - ranked only by Hodgdon (and echoed by the Wolfe/LoadData compilation). No second manufacturer's chart carries it, so the position is uncorroborated. Ranked by: Hodgdon, 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 Pro Reach (position 59)
- Hodgdon Longshot (position 60)
- Alliant 410 (position 61)
- Alliant 2400 (position 63)
- Ramshot Enforcer (position 64)
- Vihtavuori N105 Super Magnum (position 65)

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.
