Accurate
Accurate No. 11FS
Built for full-power magnum handgun loads and for small-capacity rifle cartridges, with 300 Blackout as a headline application for light, high-velocity bullets.
A flash-suppressed magnum handgun ball, slower than No. 9 and 4100, pitched at full-power .357 and .44 Magnum defensive loads where muzzle signature in the dark actually matters. It also carries .300 Blackout data for light supersonic bullets. The FS chemistry is the reason to buy it; past that there is not much of a user record to lean on.
- defensive 357 Magnum
- full-power 44 Remington Magnum
- supersonic 300 Blackout with light bullets

Grain shape
Spherical and degressive with a thick web for its speed, so it meters well and wants a case it can fill - light charges in a large revolver case are not what it was built for.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
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)
This powder is obscure enough in the US that its practical character is thinly documented. The note above is deliberately short rather than padded.
Sources
The specifications above come from Accurate's own published documentation, linked below. The two “RCM's read” sections are ours, not theirs — our assessment of what this powder is like to load, drawn from its published characteristics and from what handloaders consistently report. No manufacturer endorses them and no source below backs them. If you think we have one wrong, tell us — we would rather fix it.
