Interesting, Rich.

But then lets look at wear. Pistol is short, and uses around 4-5 grs, power. Usual muzzle velocity is around 1200 +. I think it is hard to wear out a pistol barrel. Rifle while longer uses more power and is going 10X the speed of a pistol bullet.

Examples. I load 30.06 in the 2650 fps range, .308 in the 2550fps range. My 6.5 -284 is in the 3300fps range, and I expect to only get about 1200 rounds outta it. M1 Garand barrels are rated in the amount of throat erosion. A 1 is pretty new, a 5 is pretty shot out. About 1000 rnds per number.
