Just opened up my first box of this Geco white box 5.56 NATO ammo. I noticed while loading my mags that the rounds looked more like .223 than 5.56. I grabbed another box of 5.56 American Eagle to compare them. These Geco rounds are shorter just like .223 rounds. I then grabbed a box of Frontier .223 and they are the exact same length as these Geco rounds. Anyone else came across this? The Geco rounds are stamped 5.56 NATO, but these are the only 5.56 rounds I've ever bought that were the same length as a .223 round. It's not a big deal to me. I'm just curious if this is normal for these Geco 5.56 rounds.
