Description

N550 is an excellent powder for .30-06 Springfield hunting rounds with heavier bullets, and also for other more powerful loads of 6,5×55 SE, .308 Winchester plus many others.

The N550 is tubular powder type with symmetrical grain dimensions of 1,0 mm length and 1,0 mm diameter. As with all of our N500 series powders, nitro glycerine has been added to the traditional single base powder to get better energy content. The burning rate of N550 is similar to that of the N150 rifle powder and it’s on the medium scale of our high energy powders. Higher velocity is acquired with equal pressure compared to the N100 series – without increased wear on the rifle!
