Is it ethical to use 6mm ARC for small game hunting?

April 5, 2026

Quick Answer

The 6mm ARC is a suitable cartridge for small game hunting due to its flat trajectory and high ballistic coefficient, but it's essential to consider the potential over-penetration and the need for proper shot placement.

Choosing the Right Load

The 6mm ARC’s flat trajectory makes it an excellent choice for small game hunting at ranges beyond 100 yards. For optimal performance, pair the 6mm ARC with a bullet of 70-90 grains, specifically designed for hunting, such as the Sierra 75-grain or the Hornady 80-grain. These bullets offer a high ballistic coefficient and are optimized for expansion and penetration.

Shot Placement and Penetration

When hunting small game, it’s crucial to aim for a vital organ, such as the heart or lungs, to ensure a quick and humane kill. Given the 6mm ARC’s high kinetic energy, it’s essential to avoid over-penetration and potential damage to surrounding areas or non-target animals. Aiming for a high percentage of vital organ hit probability requires a good understanding of ballistics and shot placement techniques. To minimize over-penetration, use a suitable backstop or target, such as a bale of hay or a thick log, to contain the bullet path.

Rifle and Optic Requirements

To effectively utilize the 6mm ARC for small game hunting, you’ll need a rifle that can accurately shoot to 300 yards or more. A good starting point is a well-maintained AR-15 rifle with a suitable barrel length (18-20 inches) and a high-quality optic, such as a 3-15x or 4-24x variable scope. The optic should have a high magnification range to ensure accurate shot placement at longer ranges, and a good reticle for holdovers and wind deflection adjustments.
