Disclaimer:
The barrel life estimates provided by this calculator are just that — estimates. Actual barrel life can vary significantly based on factors like load intensity, powder type, rate of fire, environmental conditions, cleaning habits, barrel quality, and individual shooting style. Wildcat cartridges and high-pressure loads, in particular, can accelerate wear. This tool is designed to give reloaders and shooters a ballpark figure based on common variables — not a guaranteed round count.
