The N140 powder was originally developed for the 7,62x53R cartridge for the Finnish Army in the early years of Vihtavuori’s history. Up to this day, it has remained one of our best-selling powder types of all time.
N140 is a tubular powder type with grain dimensions of 1,0 mm length and a 0,9 mm diameter. The structure, grain geometry, and graphite coating make it work excellently in all reloading machines and dosing is super easy. The N140 powder burns at a medium speed on our scale of rifle powders, making it a versatile handloading powder for both small game hunting and sport shooting applications.
N140 is not the choice if you try to reach the highest muzzle velocity possible, but it is certainly the choice if you try to get the best possible accuracy. This powder is a true multipurpose powder, which can be used for a large range of calibers from .223 Remington to .308 Winchester, 30-06 Springfield, and .375 H&H Magnum, just to name a few.
Reloading tip by our pros
N140 will work in many calibers but one of our favorite loads is one we tested for 6 mm BR Norma, a popular target shooting caliber with a short and fat case. We tested several charges on a 300-meter indoor range, using a high-quality yet standard case, primer, and 105 grains Scenar-L bullet. After testing several powders and charges, we found 28.5 grains (1.85 g) of N140 to be the best load. We shot four five-shot groups, with a muzzle velocity of 2736 fps ( 834 m/s). The result? The best group came in at 0.634 inches ( 16,1 mm) and the worst was 0.819 inches (20.8 mm), with an average group diameter of 0.720 inches (18.3 mm), about 0.21 MOA. Not a bad result at 300 meters!
N140 is available in containers of 1 lb (0,454 kg), 1 kg, and 3,5 kg
