A slow, high-density powder for heavy field and magnum shotshells, including long 12-gauge steel-shot loads.
A slow, high-density powder for heavy field and magnum shotshells, including long 12-gauge steel-shot strings and 10 gauge. Nobel Sport claims a progressive burn with dependable ignition across a wide temperature range, and this is the one Vectan shotshell powder flagged temperature stable here. Placed near Alliant Steel and N105. As always with the line, availability is the constraint rather than the ballistics.
- heavy steel-shot 12-gauge loads
- 10 gauge magnum

Grain shape
Small grey granular flake but dense, so it packs into a bushing at heavy payload volumes without running out of room. Flake geometry is degressive; the density and the slow burn are what keep the pressure curve under a long steel-shot column civil.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Identified by small gray granular flakes. Nobel Sport claims a progressive burn giving dependable ignition across a wide temperature range, and puts it near Alliant Steel and Vihtavuori N105. 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 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.
