[QUOTE="J E Custom, post: 2038611, member: 2736"] Throat erosion is caused by unburnt powder abrading the throat on it's way down the barrel. The length of the neck may reduce the amount of unburnt powder reaching the throat, but I believe it would be unmeasurable and would not improve the barrel life when other things like pressure, temperature and velocity have the most impact on this problem. In theory, It may sound possible but like many other things It would be almost impossible to prove. The military believes that the use of ball powder has the most effect on barrel life and throat erosion and when used this will improve. There is a better chance of them being right because I have shot range rifles with over 70,000 rounds through them that shot well. They also believe that 3,000 ft/sec or slower helps. I can vouch for well maintained and properly loaded for rifles, without excessive pressures and temperatures, barrel wear does improve Just my opinion J E CUSTOM [/QUOTE]
