- Hexagonal rifling is a type of gun barrel rifling where the traditional sharp-edged "lands and grooves" are replaced by less pronounced "hills and valleys", so the barrel bore has a polygonal (usually hexagonal or octagonal) cross-sectional profile1. The hexagonal polygonal rifling meant that the projectile did not have to bite into grooves as was done with conventional rifling2. The rifling is much tighter, being one turn in 20 inches, which means the bullet makes almost 2 turns by the time it comes out of the barrel3.Learn more:✕This summary was generated using AI based on multiple online sources.

The hexagonal polygonal rifling meant that the projectile did not have to bite into grooves as was done with conventional rifling. In 1856, that concept was demonstrated in a series of experiments using brass howitzers.
