[QUOTE="Top Cat, post: 621173, member: 4532"] Under these conditions, I think 900 rds is good barrel life. I'd toss the tube...you got your money's worth. 270 AM is a hi-performance round...if it only lasts 600 rds it's well worth it. Without actually scoping the barrel, any opinion is just conjecture...so keeping that thought in mind, theoretically, it's possible that a setback, possibly combined with a little throat lapping will give additional service life; but that effort would be something of a gamble, and I wouldn't expect a good outcome to be more than 1/2 of the original life, or 400 rds in your case. Bottom line is it's only money and it's your call, but I'd rather invest the cost of cutting, threading and re-chambering in a new tube. Consider the extra $400 as a guarantee of a good outcome, and not waste the time of someone qualified to do high level work and your own. I'm not a fan of half-way measures. Barrels are cheap...bullets are expensive! TC [/QUOTE]
