The 'FS' denotes flash suppressed: the manufacturer states the formulation includes a flash suppressant to cut muzzle signature in low light, which is the reason it is marketed toward personal-defense use. Hodgdon lists it as an extra-clean-burning powder and publishes a dedicated data sheet for it in addition to the online data centre.
Burn rate
Slower than Accurate No. 9 and 4100; charted just past Winchester 296 and ahead of IMR 4227.
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:
- Hodgdon Lil'Gun (position 72)
- Hodgdon H110 (position 73)
- Winchester 296 (position 74)
- IMR 4227 (position 76)
- Hodgdon H4227 (position 77)
- Alliant Power Pro 300-MP (position 78)

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.
