Talking about barrel replacement

At what point does a drop in accuracy make you think about replacing a barrel? How many rounds did you fire before you made that decision? Also, please mention the caliber and what you plan to use it for.

Try a thorough cleaning with stripping all copper out, and now the hard part is getting the carbon out.
Use a specific carbon cutter and then try a confirmed load again.
If it doesn’t shoot then, try to have someone scope your barrel to see what it looks like inside.
Give me a round count, barrel profile, and caliber then I can guesstimate where your barrel is, but just a guess.
Most barrels go a lot longer than people think.

As an aside, if you are thinking of buying a new barrel, understand there is legislation pending in Denver that would make barrels FFL-purchase items.

I can't say I've ever replaced a barrel because my rifle wouldn't shoot. Most of the time I've replaced because I was wanting to try something else. I've bought at least half a dozen new rifles that as soon as I got them I've removed the barrel to try something I was interested in.

On my hunting rifles I wouldn't bother to replace a barrel until it wouldn't hold under 2 MOA. 2 MOA will allow you to hunt big game in Colorado out to 400 yds easily. 2 MOA would be my standard for a 5.56 AR-15 as well. Competiton rifles I would hold to a higher standard.

Best thing you could probably do is invest in a borescope so you could gage throat erosion and heat cracking. That would at least give you an idea of when you'll be getting close to needing a new barrel. I think that would be a better indicator of needing to replace than round count.
