I consider a barrel "shot out" when it will no longer hold DOUBLE the accuracy of when it was new.
Since they usually shoot 1/4moa when new, your 1/2moa grouping is right in line with about where I would be pulling them off as well.

I typically see 308 sized 6.5's lasting about 2300 rounds before they lose peak accuracy.
Everyone screams and cries about that saying they shot theirs over 3000 rounds, but I guarantee you that if they know what they are doing, they were doubting those last 500 rounds or they have a much lower accuracy requirement.
