Developed originally for 7.62×51 NATO M80 Ball, Vihtavuori’s N135 is today a universal gun powder which is used by reloaders for a large range of calibres from .222 Remington to .458 Winchester Magnum.
The N135 is a tubular powder type with grain dimensions of 1,0 mm length and 0,8 mm diameter. The burn rate is medium on the scale of our rifle powders. Interesting fact: N135, N133 and N130 all have exactly the same grain dimensions, but due to the different surface coating the burning behaviour of the powders varies.
N135 is used especially by medium game hunters and long-range target shooters.
