You vying to be the next Sunray?
Where does a barrel wear the most? Where is the highest velocity and thus the most friction and its related heat?
The answers to these questions are that the barrel wears the most at the throat, where the velocities are the lowest. Thus if your theory was correct, the throat would experience the least wear while the area nearest the crown would experience the most due to being exposed to the highest velocities.
However the throat is exposed to the most burning plasma and thus wears the most while the crown is exposed to the least burning plasma and thus wears the least. Therefore outright velocity is not the issue. It is the amount of powder being forced down the bore that causes the wear.
See, no reason to be pisssy ...... especially when you are wrong.
Its real easy to figure out, and its not from reading posts on the internet. in 40 years of shooting the barrels I've had to change the most are the ones that shoot velocities higher than 3500fps. Speeds at 3000- 3500 fps even less, and rifles like sks and 30-30 that shoot at 2500fps - never, with tens of thousands of rounds through them.
Why does my K98 or Lee Enfeild never burn out? They have a good powder charge. In fact they use a lot more powder than my 22-250, but the 22-250 is a barrel burner? how come?
If people want to talk about compressed air, they should feel free to start another post because its not realistic and has nothing to do with normal wear and tear of traditional rifles and bullets. Whats next? quantum physics and God particles?
