Quick Answer
The 6mm ARC has a relatively flat trajectory, which can make it suitable for long-range hunting, but its downsides include limited availability of ammunition, a smaller cartridge size, and reduced bullet weight, making it less effective at longer ranges against larger game.
Ballistic Limitations
The 6mm ARC’s smaller diameter and lighter bullet weights result in reduced penetration and energy transfer at longer ranges, typically beyond 400 yards. This can be a concern when hunting larger game, such as elk or moose, where a more substantial kinetic impact is required to quickly bring down the animal. For instance, a 6mm ARC cartridge with a 105-grain bullet may lose around 1,000 ft-lbs of energy at 500 yards, making it less effective for hunting larger game.
Ammunition Availability
A major downside of the 6mm ARC is its limited availability of ammunition. Currently, there are only a handful of manufacturers offering 6mm ARC cartridges, which can make it challenging for hunters to find a reliable source of ammunition. This limited availability can also drive up costs, making it less accessible to hunters on a budget. For example, a single box of 6mm ARC ammunition may cost upwards of $50, significantly more than similar cartridges in more popular calibers.
Platform Limitations
The 6mm ARC is designed specifically for the AR-15 platform, which can limit its versatility for hunting. While the AR-15 is a reliable and accurate platform, it may not be the best choice for hunting larger game, where a more substantial rifle with a heavier barrel is often preferred. Additionally, the 6mm ARC’s compact cartridge size may require a more precise rifle setup to achieve optimal accuracy, which can be a challenge for hunters who are not experienced with the AR-15 platform.
