Vectan
Nobel Sport Vectan STL
A slower shotshell powder designed around non-toxic shot - steel, copper and similar - across a wide gauge spread.
The first of the ST shotshell family - a slower flake designed around non-toxic shot, steel and copper, across gauges from 10 through 20. Nobel Sport calls out the small light-grey granules as easy to scale and meter, which is a fair claim for a granular flake. Its limitation in the US is the single-importer channel rather than anything about the powder.

Grain shape
Small granular flake: degressive like any flake, but fine granulation gives more consistent volumetric drops than a large plate flake and lets it settle evenly into a bushing.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Identified by small light-gray granular flakes that Nobel Sport describes as easy to scale and meter. First of the four-powder ST family. Vectan is French-made Nobel Sport propellant; Shooters World is the current US distributor and publishes the US load data.
This powder is obscure enough in the US that its practical character is thinly documented. The note above is deliberately short rather than padded.

The specifications above come from Nobel Sport Vectan'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.
