This calculator can be used to find bullet impact energy to determine if a round is safe to use at the SCC indoor pistol range.
You can submit this information to the board to be approved for downloaded rounds in restricted calibers. For example, a bullseye shooter might load .357 Magnum brass with a reduced powder charge that results in a safe level of bullet energy.
Note: This calculator ignores any bullet slowdown caused wind resistance since at only 50 ft., it should be negligible.
This is NOT an all inclusive list. If something isn't listed, please ask.
