What is 5R Rifling?

Retired Army man, Barrett “Boots” Obermeyer developed 5R rifling as a gunsmith in his family’s store and 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 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 angled form of the lands also helps to reduce jacket failures in quick-twist barrels.”

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