Shipping was fast, so I liked that

This is the way to go when buying 5.56. Already loaded onto stripper clips

I recover for reloading and they are super consistent.
Common concerns
Short Round Count8%
Not 400 rounds. 392. Not that 8 rounds is going to kill me but this is part of the reason I don't buy in bulk.
High Current Prices8%
Ridiculously expensive. I wish I could go back to 2018 and order a hundred cases when they were less than half the price they are now.
Shipping Costs High2%
The only complaint I have is and I am sure this company has to charge a shipping fee, it is pretty high.
Rebate Issues1%
You never get your rebate. The site malfunctions and support does not help at all.
Frequently Asked Questions
Federal 5.56 Ammo for Sale
Is Federal 5.56 ammo good?
Federal 5.56 ammo is reliable and accurate, making it a solid choice for training and range use. American Eagle is their most popular line. For defensive or hunting use, opt for their soft-point loads rather than standard FMJ for better terminal performance.
What's better, 55gr or 62gr?
55-grain shoots faster with a flatter trajectory; 62-grain penetrates better. For training, 55-grain costs less. For defense, 62-grain handles barriers better. Match your choice to your rifle's twist rate—most modern 5.56 barrels use 1:7 or 1:8 twist, which handle both weights well.
What grain is military 556?
Military 5.56 NATO typically uses 62-grain bullets, designated M855. It features a steel penetrator core for barrier penetration. Some special operations units use heavier 77-grain loads like the Mk262 for better long-range accuracy.
Why can't you put 556 in a 223?
Firing 5.56 NATO in a .223 chamber carries real risks. The 5.56 runs at higher pressure than .223 Rem, and its longer lead can cause throat erosion and dangerous pressure spikes in a .223-rated firearm. Use a rifle chambered in 5.56 or .223 Wylde if you want to shoot both.
Is 5.56 NATO and 5.56 X45 the same?
Yes, 5.56x45 and 5.56 NATO are the same cartridge. The "x45" refers to the case length in millimeters. Both terms describe identical ammunition with the same dimensions and performance. You can safely shoot either designation in any rifle chambered for 5.56 NATO.
Does Federal still make 5.56 ammo?
Yes, Federal still makes 5.56 ammunition, primarily under their American Eagle line. It's widely available across numerous retailers in quantities ranging from 50 to 1000 rounds, with pricing varying by load and quantity.
