For example, a certain powder type can act slightly quicker than some other powder type, when used in 308 Winchester loads however, when these powders are used in 7圆4 loads, evident burning rates might reverse. Ranking differences result from use of different criteria. Still, each such chart tells 'the truth'. When comparing different burning rate charts, one will notice variations in listed propellant ordering. Also make sure that you close the powder container properly afterwards.Ĭartridges should be stored under the same ambient conditions to maintain their quality. If the air is too dry, it will dry out the powder, which will cause the pressure to be higher, thus affecting performance. Where possible, store the powder at a constant temperature, ideally between 12 and 15☌, and a relative humidity of 40–50%. To maintain the product quality for as long as possible, you have to keep the powder in a suitable place under suitable conditions.
