Vihtavuori N100 Rifle
Vihtavuori N165
Built for magnum rifle cases running heavy-for-caliber bullets, in long-range shooting and big-game hunting.
N160 with a heavier deterrent coating, for the heaviest-for-caliber bullets in magnum cases: .338 Lapua, .300 Winchester Magnum, .416 Rigby. It buys a little more velocity than N160 with heavy bullets by keeping the pressure curve flatter for longer. Worth noting if you chose N160 for its decoppering and temperature-stability claims and are stepping up: Vihtavuori makes neither claim for N165.

Grain shape
Same grain dimensions as N160, with only the surface treatment differing, which makes this the cleanest illustration in the line of deterrent coating rather than web thickness setting burn rate. Neutral-burning single-perforated tube.
Why geometry decides burn rate more than chemistry does: Shape Is the Product.
Same grain dimensions as N160 with a different surface coating that slows the burn and allows slightly higher velocity with heavy bullets.
Burn rate
Very slow; on the chart it falls after N560 and before N170.
Chart agreement: consistent across charts - listed in the same relative neighbourhood by every publisher that carries it Ranked by: Hodgdon, Vihtavuori, Shooters World, Wolfe/LoadData.
