N135 - the universal rifle powder
Developed originally for 7.62x51 NATO M80 Ball, Vihtavuori's N135 is today a universal gun powder which is used for large range of calibers 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. Fun fact: N135, N133 and N130 all have exactly the same grain dimensions, but due to the different surface coating the burning behaviour of powders varies!
N135 is used especially by medium game hunters and long-range target shooters.
N135 is an excellent powder for .308 Winchester loads with a bullet weight between 8,0 g / 123 gr and 10 g /155 gr. If you have never tried N135 with a 155 gr OTM bullet, it's time to do it! Try this powder also with .223 Remington loads with a bullet weight of 3,9-4,5 grams (60-69 grains) and you will be surprised of the accuracy and velocity performance of the combination.
