5 R rifling, with its odd number of lands and grooves has each land opposing a groove. It also has radiused groove corners, supposedly giving a better gas seal.
It has been claimed that 5 R rifling deforms a bullet jacket less than 6 or 8 groove rifling. For long range shooting this supposedly helps the bullet retain its original shape for better flight characteristics.
So, what are the real world internal and external ballistic advantages of 5 R rifling?
