[QUOTE="David Urasky, post: 2141859, member: 108550"] People tend to look at 5R profiles as being superior rifling. The benefit to using a 5R profile is easier cleaning. With the tapered edges of the rifling crap doesn't get stuck in a sharp corner as on a traditional squared edge rifling. As far as performance is concerned, there's no real benefit. I use them for my competition rifle where I'm shooting a couple of thousand rounds a year. My hunting guns getting maybe 50 rounds per year have traditional rifling unless I happen to have a 5R on the shelf. Talk to the barrel manufacturer. Shuch as for my 20Tactical, Bartlien recomended a 4 groove traditional rifiling barrel. But I don't even know if 5R is available in 20 caliber. [/QUOTE]
