This is a simple calculator for bullet reloading. Type in the muzzle velocity that you want to get, and the Bullet Load Calculator will estimate the amount of powder charge that you need to load. All you have to do is enter a few pieces of information about the specifications of your bullet/powder/firearm combination.

Input:
Desired Muzzle Velocity
Bullet Weight
Minimum Load Specs: Powder Charge and Muzzle Velocity
Maximum Load Specs: Powder Charge and Muzzle Velocity

The calculator finds:
Suggested Load Amount
Muzzle Energy

It also provides rough estimates for:
The Total Energy from the Powder
The Energy Lost (due to heat, friction, etc.)
The Energy Density of the Powder
The Energy Efficiency
