6.5mm

6.5mm (.264 bore)

History & Design Intent

The 6.5mm / .264-inch bore has a century-long pedigree in European military and target rifles, but the modern American resurgence came with cartridges like the 6.5 Creedmoor (Hornady, 2007), engineered specifically for long, high-ballistic-coefficient match bullets in a short, efficient case.

Operational Profile

The 6.5mm bore launches long, sleek bullets (typically 120–147 grains) that resist wind and retain velocity downrange, delivering long-range accuracy with notably manageable recoil. It is a favorite for precision rifle competition and medium-game hunting where a flat, predictable trajectory matters more than raw bullet mass.
