[QUOTE="Bart B, post: 362092, member: 5302"] I think Barret (Boots) Obermeyer first used this in his cut rifled barrels for the 7mm Rem. Magnum barrels. Sierra's jackets on their 168 gr. 7mm match bullets were thin enough to be weakened too much by conventional rifling; they came apart spinning so darned fast. Obermeyer dubbed it "5R" and the rest is history. I've used some 30 caliber 5R barrels from him in competition; great accuracy and decent barrel life. [/QUOTE]
