again, different testing parameters, but they were adamant about the effect of the harder jacket:If that article can be compared to the bullets in question, it would scare me!! 6,000 rounds vs 10,000 is pretty significant. That would mean a 2000 round rifle would last 1200. Just sayin'
We don't know if those bullets we're comparable at all but I think it bears questioning.
"At the end of the test, the chrome lining of the Wolf and Brown Bear barrels was almost gone from the throat forward, and the barrels had effectively become smoothbores, with the rifling near the muzzles acting only as a mild suggestion on the projectiles. A throat erosion gauge could be dropped into the bore from the muzzle end with absolutely no resistance.......The difference lies with the projectile – the soft copper jacket of the Federal ammunition simply doesn't cause the same amount of wear as the bimetal (copper and steel) jacket of the Russian ammunition."
