[QUOTE="Greyfox, post: 899731, member: 10291"] I will stick my neck out and claim that I have yet to see a correlation between the amount of visible copper at the end of at barrel and the number of accurate rounds that can be fired between cleanings with either custom or factory barrels. I have seen a difference in how much time and effort it takes to clean the rifle. Clearly the tooling marks typical in many factory barrels are notorious for copper build up and can take a long time to get clean. I have customs that have little if any visible copper, that clean very quickly. After many years, and four Remington Milspecs with R5 in 308(1-300WM), I have found that this barrel, when broken in properly, will hold it's accuracy spec(.25-.5MOA) for at least 200 rounds and clean up quickly. I just happen to pick 200 rounds as a cleaning interval, it may very well go longer) The accurate life of approximately 2500 rounds seem to be unaffected by cleaning intervals. These rifles are generally shot very hot in the summer months with as many as 30 rounds every 30 seconds in long range competition.
