So a couple months ago I bought a new Savage 10FCPXP in .308. I have had it a couple months so now it's time to get something new. (That's the way I roll) Probably just a barrel swap will curb the itch for a while. I want to go to some sort of 6.5mm bullet. I came across Pac-Nor barrels. They seem to be a little more expensive but they offer a polygonal twist. Does anyone else have a polygonal twist? Are they all that and a bag of chips? Or are they a passing fad that will blow over. I am envisioning longer barrel life, faster cleaning, etc... A lot like a glock barrel where it has been said that they can't be "shot out". Any truth to all this anecdotal rhetoric? Or is it all a sales pitch?
