Norma's page describes application only; grain geometry and base are not stated. Norma canister powder is not stocked by the mainstream US reloading distributors and reaches US shelves only through occasional imports - treat availability as unreliable. Many web shops that appear to list Norma powder in the US are not legitimate retailers. Norma publishes data through its own reloading portal rather than a printed US manual.

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.
