Does rifling increase range?
The spin imparted by rifling significantly improves the stability of the projectile, improving both range and accuracy. Typically rifling is a constant rate down the barrel, usually measured by the length of travel required to produce a single turn.
Why is a spinning bullet more accurate?
Rifling helps impart a spinning motion to a bullet when it’s fired. A spinning bullet is much more stable in its trajectory, and is therefore more accurate than a bullet that doesn’t spin. This is exactly why is is better to throw a football in a spiral.
What is the best rifling twist?

of the rifling lead. On big bore rifles with heavy bullets (400+ grain) 8 groove is recommended. My personal preference in rifling/groove count depending on the rifle bore and bullet weight to be used is 3 groove for ultra high velocity cartridges using light bullets ( 75 grains or less ).
What is your preferred rifling/groove count for rifle barrels?
