Powder body weight and quantity are only two of several aspects influencing The inner ballistics of a cartridge. The proper utilization of burn rate charts is to seek out propellants with related burn rates. As a result, if H4895 is a favourite of yours for loading a selected cartridge, however, you run away from that powder or choose to check out an identical powder, it is possible to seem to find out what other powders have burn rates similar to H4895.
