Bullet weight and the specified efficiency of the spherical play a necessary half within the powder choice. Heavier bullets usually require slower-burning powders to realize optimum velocity and strain inside protected limits. A bullet’s supposed objective – looking, goal capturing, self-defense – additionally influences the powder selection.
The Burn Charge Equation
As talked about earlier, burn charge is essential. The reloading guide suggestions will counsel a perfect vary of powders for a given bullet and cartridge. At all times stick to those suggestions, as choosing the fallacious burn charge can result in harmful strain ranges and poor efficiency.
Manuals because the Guiding Star
At all times, at all times, at all times seek the advice of a dependable reloading guide. Reloading manuals are your bible. They supply particular load knowledge for numerous bullets, powders, and cartridges, together with powder cost weights, general cartridge size (COL), and most pressures.
