Home Forums Hunting & Shooting Long Range Hunting Is 5R rifling the real deal?

As for barrel cleaning, I've found a couple of Extreme Weather Model 70s copper foul far less than most factory barrels. I can't say my 5R Remingtons are any better in this regard, though they are probably the same about the same. Lack of fouling may be due more to general improvements in barrel making rather than a particular rifling style.
