Rifling FAQs:

Q: Is a rifling the helical groove pattern that is machined into the internal surface of a gun's barrel?

A: Yes, for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting.

Q: Is a rifling a constant rate down the barrel?

A: Yes, and usually measured by the length of travel required to produce a single turn.

Q: Is a rifling currently seen on pistols from CZ?

A: Yes, and Heckler & Koch, Glock, Tanfoglio, and Kahr Arms, as well as the Desert Eagle.

Q: Is a rifling eroded through repeated rifling engagement?

A: Yes.

Q: Was a rifling used as early as the American Civil War?

A: Yes, Colt Army and Navy revolvers both employed gain-twist rifling.

Q: Was a rifling invented in Augsburg?

A: Yes, and Germany in 1498.

Q: Is a rifling 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" , or "1 turn in 254 mm"?

A: Yes, A shorter distance indicates a "faster" twist, meaning that for a given velocity the projectile will be rotating at a higher spin rate.

Q: Is a rifling to deliver the projectile accurately to the target?

A: Yes.

Q: Is a rifling handled by the throat of the chamber?

A: Yes.
