[QUOTE="Mikecr, post: 1456389, member: 1521"] Technically, barrel life is endless. Even with all rifling gone, the barrel will still function. 'Accurate barrel life' is completely different. On that: Barrels don't wear out to cause loss of accuracy. This is shot out via formation of carbon constriction. And this does NOT reduce barrel life. This is exactly what we need. The throat area is heat damaged most, while the muzzle area is not heat damaged at all. Fire lapping at least addresses the roughest part of our bores, and no more. Now if you're trying to address a loss of lapping near the muzzle, perhaps copper fouling up in excess because it's too smooth, then fire lapping wouldn't help. That's true. But by then you're way past the accurate life of that bore. [/QUOTE]
