The 6.5 Creedmoor has a similar advantage over the 6mm Creedmoor in kinetic energy. Take that for what you will, but no animal will be able to tell the difference between an additional 100-200 ft-lbs of energy with a well placed bullet though.

Since this article is focused on the performance of these cartridges for hunting, I didn’t include any ballistic data past 500 yards in the table above. However, just to give you an idea of the superiority of the 6mm Creedmoor over the .243 Winchester at long range, consider this: the .243 Winchester has over 30″ more bullet drop than the 6mm Creedmoor at 1,000 yards when both cartridges have a 200 yard zero.
It was in 2007 when John Snow, a columnist for Outdoor Life, made the decision to publish an article on how to create a wildcat cartridge that started the ball rolling for the narrative of the 6mm Creedmoor. Snow was a major enthusiast of shooting at long distances, so the brand new 6.5mm Creedmoor cartridge that had just been produced that year particularly piqued his interest. In the end, he came to the conclusion that the best way to create a new cartridge that could shoot 6mm bullets with even less recoil than the parent cartridge had been to use a 6.5 Creedmoor case that had been necked down. This would allow the new cartridge to be accurate out to a distance of 1,000 yards.
Snow combined the new cartridge, which was at first known as the 6mm HOLE (Hornady-Outdoor Life Express), with a custom rifle that had been constructed by George Gardner of GA Precision in 2009. Both the rifle and the cartridge worked exceptionally well, and Snow’s article about the entire undertaking was published in the August 2010 issue of Outdoor Life.
Despite Snow’s decision to go on to other projects, the saga of the 6mm Creedmoor was not over there. A few years later, when Gardner was considering ways to get an advantage in the new Precision Rifle Series competition (PRS), which was quickly gaining popularity, he recalled the project he and Snow had worked on together.
Shooters participating in PRS contests are required to immediately engage targets at a variety of ranges, some of which extend over one thousand yards. Because the competition is timed, getting a hit in the first round is desirable; nevertheless, there is more to these competitions than having a tiny shot group.
It is also incredibly beneficial to have the ability to make quick follow-up shots and rapidly adjust your aim after missing the target. In addition, shooters are not permitted to use bullets with a diameter greater than.308 inches or a velocity greater than 3,200 feet per second. Because of these factors, cartridges that have a long barrel life, low recoil, flat shooting, medium bore, moderate velocity (up to a point), and mild recoil have a significant edge in these events.
Gardner came to the conclusion that the 6mm Creedmoor was the ideal caliber for use in the PRS, so he modified an AR-10 so that it could accommodate the new cartridge. Other competitors in the PRS events that year took note of how well the rifle and cartridge performed and began placing orders with Gardner for 6mm Creedmoor guns. In the years that followed, there was a precipitous rise in the demand for the new cartridge.
Best 6mm Creedmoor Ammo For Hunting
Unlike its bigger brother the 6.5 Creedmoor, there aren’t many options for factory 6mm Creedmoor hunting ammo right now. The list is slowly growing, but there are currently only a handful of options for loaded rifle ammunition the 6mm Creedmoor. Among others, this list includes the 103 grain ELD-X from Hornady, the 95 grain Barnes LRX BT, the 87 grain Hornady V-Max, and the 100gr Sierra GameKing.
