The N550 is a tubular powder type with symmetrical grain dimensions of 1mm in length and diameter. Nitroglycerin has been added to get better energy content. The burning rate is similar to that of the N150 rifle powder. Higher velocity is acquired with equal pressure compared to the N100 series without the extra wear on the rifle.
