If it was a headspace issue you would be rupturing case heads or getting balloned brass. And if it is a factory barrel chances are it came from Remington good to go. Headspace does not change unless the gun/bolt has been played with.
I dont know of anyone in Denver that I would recommend. I do not recommend Black Ops in Montana thats for sure.
