I have some questions about the 30 BR. I was wondering if the 30 BR is as accurate as the 6br. and also, what is the max range? Can it shoot 600 yards very well? Do they make a 30br improved? I like the barrel life on the 30BR, but i want to shoot 600 yards. Should i just forget the 30BR and just go with a 6br or brx? Thanks for the impute.
