Consistent sub MOA groups with a Fulton Armory AR-15 A2, SS match barrel 1:9 twist. Compared to similar match loads by Black Hills, Remington and Hornady; factor of 2 improvement on accuracy with this Federal ammo. Ammo.com get more of this into stock!

I have tried a number of rounds from flat base hollow point to ballistic tip's but I was not satisfied with the results. So, I tried the 69 grain BTHP match, I was very pleased with the results, much more consistent, however purchasing massed produced ammo for accuracy is not the way to go. If you shoot a lot, reloading your own ammo is the best way to ensure that every round is the same. I feel the value of the ammo is about average in cost. What I paid for the 40 rounds from ammo net including shipping I could buy the same at a local store, so not really a savings.

Bullet strength and bullet placement are key factors,. I wouldn’t recommend all 223 for big buck deer,. Only a few will do the trick ,. It takes a powerful vital hit to bring a buck down,. The penetration and shock wave is what’s needed to take the game down ,. Choose your caliber wisely ,.
