4500-6000 is an average sub moa round count for 308. gilt edge accuracy often doesn't last much longer than 3500-4500 though...
But it means a few tubes would be 10-15K for sure.

Pretty easy if you shoot like I did, around 8K a year.

A good bolt gun in 308 with a scope should be shooting 200s IE perfect scores with high x counts almost every time out at 600... Its what a good gun and shooter can do... frankly hitting a 12 inch target at 600 yards isn't very hard to do.
