Eagle Eye Precision Ammunition – Sin City Precision

Hand loading is synonymous with long range precision rifle shooting. We have all heard “consistency is accuracy,” which is a continuous theme in our sport and printed on every box of Eagle Eye Ammunition. That saying applies to more than just your ammunition when shooting long range. Many of us hand load because traditionally, we can produce higher quality lots of ammunition for our rifle than we can purchase. Hand loading is a time consuming process and it seems you either love it or hate it. I fall into the “hate it” category but because of my passion for practical long range precision rifle shooting, I spend a lot of time behind the reloading press.

Those of us who prefer to purchase our ammunition rather than load it, buy “match grade” ammunition. Match grade refers to ammunition suitable for competition use. But sometimes simply changing the projectile used in the ammunition is enough to deem it match grade. This is where Eagle Eye Ammunition is different. They are a Six Sigma company, meaning the quality control of the product is built into every aspect of its production. They use a set of techniques and tools that allow them to maintain a very small bell curve when measuring variances in their components and finished product. I’m not going to pretend to know exactly how the quality assurance process works but if you would like to know more, I suggest reading the explanation from The Firearm Blog under “Warning- Science Ahead.” They did a great job in explaining how Eagle Eye Ammunition ensures an extreme level of quality control. That level of quality control combined with top of the line components allows Eagle Eye to produce very accurate and truly match grade ammunition. Where does Eagle Eye get their components? They manufacture their own .223 and .308 brass along with .308 projectiles. Creating these components in house and applying their QA program, the manufacture of the components further ensures the performance of the finished product.

What do the best components and an extreme level of quality control get you? Also printed on the box is their 0.5 MOA guarantee for both their .223 Remington and .308 Winchester ammunition. That is a pretty lofty guarantee especially when considering the variables in different rifles and the liability associated with ammunition. They have to produce .223 Remington and .308 Winchester ammunition that will safely function and fire in every rifle chambered for those cartridges. To achieve the 0.5 MOA guarantee, we expect low extreme spread and standard deviation numbers. Which “proof of” can be found on the Eagle Eye Facebook page. We also expect consistency throughout the different lots of ammunition produced. If you visit their website, you will learn that Eagle Eye Ammunition uses actual shooters and factory rifles for the final testing of each lot of ammunition they produce! This is a very practical manner to test the ammunition and uphold the 0.5 MOA guarantee.

Testing w/ my AR-15.

When the ammunition arrived, I was excited to open the package. I already had a few things in mind that I wanted to do. First, I wanted to see how consistent the weights of the loaded cartridges were. To have a comparison or bench mark I first weighted 20 of my hand loaded 6.5mm Creedmoor rounds left over from the Sin City Precision monthly practical LR rifle match. I shoot and reload a lot of 6.5mm Creedmoor. My reloading process is not nearly as involved as what a Bench Rest shooter might do but I do carefully weigh every charge and do my brass preparation in phases by lot. This allows me to ensure every case has had the same process done to it; de-prime, clean, lubricate, FL resize (0.0015”-0.002” head space bump), trim/chamfer, re-prime, charge and seat projectile. This method allows for me to also maintain a 0.5 MOA or better accuracy without spending too much of my free time reloading. To me, the task is still arduous especially when loading 200-250 rounds in preparation for a Precision Rifle Series match.

6.5mm Creedmoor Hand Load Results (measured in grains):

Median: 334.1

Mode: 334.5 (20% of cartridges weighed)

Mean: 334.4

Spread: 7.4

.308 Winchester Eagle Eye Ammunition (measured in grains):

Median: 393.2

Mode: 393.5 (15% of cartridges weighed)

Mean: 392.9

Spread: 3.6

.223 Remington Eagle Eye Ammunition (measured in grains):

Median: 195.6

Mode: 195.8 (20% of cartridges weighed)

Mean: 195.5

Spread: 1.2

The spread in weight is what I’m really paying attention to. Across 20 hand loaded 6.5mm Creedmoor rounds, the difference from the lowest weight to the highest weight was 7.4 grains. The spread in loaded rounds contains all the combine weight variances in – primer, brass, bullet and powder charge. After measuring 20 rounds from the first package of Eagle Eye .308 Winchester ammunition I pulled out of the box, I was surprised by a spread of only 3.6 grains. That is less than half the spread from my hand loaded 6.5mm Creedmoor ammunition. The Eagle Eye .223 Remington ammunition was especially impressive with a weight spread of only 1.2 grains!
