Barrel life estimator

Project how long a barrel will stay match-ready using your charge weight, velocity, and usage cadence. Get a target replacement date with a single click.

Select the closest cartridge profile. Its baseline barrel-life estimate is adjusted by charge, velocity, and firing pattern.

Baseline life and reference velocity are prefilled per caliber.

Average powder charge per round for the load most often fired through this barrel.
Representative measured average velocity for the load. Higher velocity generally increases throat erosion in this estimate.
Best available count of live rounds fired through this barrel since new.
Long-term average weekly volume used to estimate a calendar replacement window.
Choose the firing cadence that best represents use. Long rapid strings retain heat and usually accelerate throat wear.

Higher pace reduces life slightly to account for heat.
