Durability relies on both the treatment/lining + the base metal. If you have a weaker substrate metal you are going to get much faster barrel erosion once the propellant gasses eat through the treatment/lining in the thoat area and leade of the rifling.

Thanks vicious..I am wanting accuracy over durability for this build. And I appreciate the word on GM, Hulkstr8.
The obedient always think of themselves as virtuous rather than the cowards they really are.
