WHAT IS 5R RIFLING?

Retired Army man, Barrett “Boots” Obermeyer developed 5R rifling as a gunsmith in his family’s store. Boots holds a High Master Classification in both high-power rifle disciplines, is a Distinguished Rifleman, and has won numerous shooting awards at both state and national levels. The best definition of 5R rifling comes from “Boots” himself …

“5R is the form of rifling I developed for use in most target barrels and in many sporting barrels,” he explained. “These barrels have 5 grooves, and the lands have angular sides. I have observed that bullet jackets will deform such that they remain closer to the R-form lands than they will to the sharp-edged lands present in conventional-style rifling. This reduces powder fouling at the corner of the grooves. The land’s angled form also helps reduce jacket failures in quick-twist barrels.”

The diagram above of rifling profiles shows the difference between traditional rifling (top) and 5R rifling (bottom). Because the edges of 5R are not square, they don’t cut into bullet jackets as much, and, with 5R rifling, the lands are opposite of grooves, while with traditional rifling, lands are opposing lands, and grooves are opposite grooves.
