Nobel Sport Vectan ST3XL
The slowest ST-family powder, engineered for the heaviest shotshell payloads and specialty magnum loads.
The slowest powder in the Vectan shotshell line, for the heaviest payloads and specialty magnum loads in 10 and 12 gauge. That is genuinely all that is published about it - no US user record, no named comparison powders, and the same single-importer channel that constrains the whole Vectan range.
- heaviest 12-gauge payloads
- 10 gauge magnum

Grain shape
Grey granular flake with the thickest web in the ST family, which is what puts it at the slow end - same geometry as its siblings, more wall for the flame to burn through.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Identified by gray granular flakes. 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.
Sources
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.
