Rifling Rifling in a .35 Remington microgroove rifled barrel. Rifling consists of helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.ifling is often described by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as 1 turn in 10 inches (1:10 inches), or 1 turn in 254 mm (1:254 mm).
