What's so special about XM193 ammo? I see lots of people love that stuff for .223 ... what makes it better then any other .223 ammo? I'm waiting on my sig 556 to come in and bought some .223 already, but wanted to know what I'm missing out on.

Its a little hotter than .223. It also has a slightly longer casing, to hold that extra helping of powder. Consider it .223 +P, speaking in 9mm terms.

XM-193 is 5.56mm spec ammo, and is not .223. There is a difference in specifications, pressures, and performance.

Since you purchased a Sig 556, you can shoot either 5.56mm ammo, or .223 ammo out of your rifle. Do not shoot 5.56 ammo from a rifle chambered in .223.

XM-193 is not match quality ammo, but it is mil-spec and the closest thing civilians can get to the M193 ammo that the US .gov issues to our troops. With crimped sealed primers and sealed necks, it's great ammo to stash away for a rainy day.

Military contract ( Lake City ) ammo made for the civilian market I believe. Excellent stuff and pretty good accuracy. I shoot a steady diet of this through my AR and it has performed flawlessly.

M193 with a 55gr bullet is supposed to be around 3250fps from a 20" barrel which is faster than regular commercial .223 loads. M193 is what was used in the military before they adopted the 62gr bullet. It comes out of the barrel faster than the 62gr stuff but since it is lighter it loses momentum quicker and trajectory starts to drop off faster past 300 yds. From what I read, the type of bullet used in M193 fragments in soft tissue at velocities higher that 2500fps. The commercial 55gr bullets usually do not fragment as well/if at all. Go and read the Ammo Oracle website theres alot of info there.

If you are going to buy 1000 + rounds for a "rainy day" (or for the zombies), this is the stuff to get.

First ammo I shot out of my AR was XM193 and it was great! 500 rounds without a singe problem. Then I got some .223 and it just wasn't the same. There's a noticeable difference in kick and just seems to shoot a lot better in my AR. I've been dying to get some more but the prices are pretty crappy right now. Cheapest I've seen lately is about $235 shipped for 500 rounds.

Yes, used to be that lake city xm193 was the great buy. That has changed slightly, but still it is a must have for plinking around. BTW some "operators" prefer it over m855 62gr for close up work out of m4forgery type systems.

It's also good for longer term storage, since it's sealed at the primer and neck.
