I have a Remington 700 sfii barrel that started life as a 7mm mag, roughly 300 rounds, then I had it reamed out to 28 nosler that I shot 30-40 times ( got it down to .75moa) and have since then changed barrels. Still a very nice barrel without throat erosion. I also has a bastard muzzle brake that was ordered for it and never installed I would make a deal to buyer $180tyd
