7 STW barrel life

[norm82]

What kind of barrel life should I get out of my STW? I shoot a 180gr berger bullet. I use 76gr of H1000. Muzzle velocity is 3045fps. Any thoughts?

all depends on the barrel steel, how you clean it, and how you treat it... Anywhere from 800 rounds to 1500 rounds. I was at 1400 rounds on my last stw and though the bore showed shallowing at the origin, it was still shooting better than my current rifle, which has around 500 rounds on it... The new rifle, incidentally, is showing little bore wear at all yet.
