[QUOTE="BallisticsGuy, post: 1293032, member: 96226"] Barrel life is going to depend on rate of fire, powder choice, powder weight burned and how high the pressures are; where bore diameter is a constant. That said, it's actually something you can make a good fist of calculating if you have the maths. If you go with something like H50BMG then my numbers say about 550 rounds if you let it cool between shots and clean every few rounds. H50 is a very energetic powder apparently and the 28N is a massively overbore cartridge. If you use something like H870 then my maths say just north of 700 rounds. Those numbers come from an equation and are not gospel however it has been very very accurate over the course of a number of barrels. [/QUOTE]
