[QUOTE="MudRunner2005, post: 1247114, member: 12995"] Yes, there are many other factors that affect barrel and throat life. Powder burn rate is one of them. You only mentioned 3 factors, and only 1 of those 3 three you mentioned truly affects barrel life...Which is neck length. Steeper shoulder angle affects brass life and cartridge/burn efficiency in a positive way, but has not been shown to have much affect on barrel life. And cartridge length vs. width has zero to do with barrel life. Cartridge capacity regardless of cartridge shape and design, affects barrel life. Now, cartridge shape and design does affect functioning efficiency of the cartridge. [/QUOTE]
