Home Forums Hunting & Shooting Gunsmithing Barrel life expectancy per cartridge

Too many variable involved to make predictions. First you have to define "barrel life" and then you have to consider the number one enemy to the barrel, heat and pressure.

Everyone has a different take on what they consider acceptable accuracy which will increase or decrease the numbers. For instance, 22 LR's can go much further than 5-10K, while 223 types can burn out in less than 1K. A lot of it depends on how well you treat the barrel.
