Hello all, I am new to the .223 / 5.56 world, as I just got a SCAR-16S. I haven't even shot it, yet! But, I'm stocking up on ammo. I bought some Walmart Federal 100-value packs in .223 for $39.97 for a 100-round value pack a few weeks ago. Last night, I bought some American Eagle (AE223 made by Federal) 100-round value packs at Gander Mountain, on sale, for $29.99. (A pretty good deal, I think.) Visually (to my eye), the cartridges are IDENTICAL. Both are 55-gr. The only thing different is the graphics on the boxes. Is there a difference between the two (I'm not aware of)? Thanks for any education you all can impart on me! Mike Wanna kill these ads? We can help!
