Frequently Asked Questions
5.56 Match Ammo - 55 Grain
What is better, 55 grain or 62 grain?
Neither is universally better—it depends on your rifle's barrel twist rate. A 1:12 twist stabilizes 55-grain rounds well, while 1:7 or 1:8 twists favor 62-grain. The 55-grain shoots faster with a flatter trajectory; 62-grain penetrates deeper. Match your ammo to your barrel for best accuracy.
What grain 556 does the U.S. military use?
The U.S. military standard 5.56 NATO round is the 62-grain M855. Special operations units also use the 77-grain Mk262 Mod 1 for improved accuracy and range.
What grain is 5.56 for deer?
5.56 NATO isn't ideal for deer hunting. Those who use it typically choose 60–68 grain soft-point or bonded bullets for better expansion and penetration. Many states restrict it for deer due to limited energy. A larger caliber like .308 Winchester is a more reliable choice for clean kills.
How much do 500 rounds of 556 cost?
Five hundred rounds of 5.56 NATO typically cost around $248–$275 based on current pricing, with per-round costs running roughly 45–51 cents. Prices vary by brand and bullet type, ranging lower for budget options and higher for premium ammunition. We currently stock 43 variants across 46 retailers.
What is 55 grain 556 good for?
55 grain 5.56 is best suited for target shooting, plinking, and general practice. It's affordable, widely available, and produces mild recoil. It works adequately for varmint hunting at moderate ranges. For home defense or larger game, heavier 62–77 grain loads are more effective.
Is 5.56 NATO and 5.56 X45 the same?
Yes, they're identical. 5.56x45 is the full metric designation (5.56mm bullet diameter, 45mm case length), while 5.56 NATO is the military standard name. Both refer to the same cartridge and can be used interchangeably in a 5.56 NATO chambered rifle.
