Internal Ballistics; Propellant Burn Rates, Matching Powder to Expansion Ratio & More

As we explore shooting sports we are introduced to various propellants. Propellants, smokeless powder is a nitrated cellulose. Early propellants were heavily based on nitrated cotton, or ‘gun cotton’ used mainly in artillery. Modern powders are single based nitrocellulose while double based powders have a dash of nitroglycerine to up the potential chemical energy. Most…
