Re: Anyone burned out a custom barrel?
yes, I've shot out several hundred over the years. You're asking a question that's far too broad here. I've had many that went up to 3-4 thousand rounds. I've had others that were gone in less than four or five hundred rounds. The chambering, intensity of the load and bullet weights involved all go into this equation. Perhaps most importantly, what is "shot out"? That's a question that only the shooter can answer, and it'll vary wildly from one shooter to the next. What a Marksman Long Range shooter considers perfectly acceptable, a High Master would have pulled long before. In my case, when using these barrels for testing, I HAD to have ten-round 1/2 MOA groups, consistently, without fail. As soon as they lost that edge, I pulled them, since they weren't worth my time to mess with anymore. I always had several guys who would be waiting for my take off barrels, to be redone as hunting rifles. Many of them went on to very long and happy hunting careers after they were and the guys were always happy to get them.
Like I said, there's several questions more that need to be answered here, before you can really get any kind of definitive answer to this one.
