[QUOTE="41mag, post: 353198, member: 3804"] Description taken from the following, [url=http://www.snipercountry.com/inreviews/rem_m700_stainlessspecial5rmilspec.asp]The Remington Model 700 Stainless Special 5R Milspec[/url] "5R-rifling features a radius'd shoulder between the lands and the grooves. Advantages are claimed to be a smoother engraving transition on the bullet jacket which, in theory at least, creates less drag in flight - which means possibly a slightly flatter shooting bullet compared to a bore of standard rifling profile. The second benefit is cleaning. Without the 90-degree angles between lands and grooves, fouling seems less likely to adhere as tenaciously to the bore. Copper fouling may also be reduced. This rifling profile is used in the Army's M24 Sniper rifle.
