Hey Im a bit confused. Anyone know the difference between the lake city 193 and the "regular" federal xm193? Is there a difference? I think the Lake City is manufactured by Eagle... Do you perfer one over the other? Its for a Bush shorty and im open to other suggestions for ammo as well..Im looking to buy a case of 500 so I want to get it right...Mainly using the gun for range/fun shooting but would like it for the HD situation as well. Thanks!

For just goofing around at the range and Home Defense, you won't notice much difference. It's basically all good ammo. Having said that, you should be aware that .223 ammo and 5.56 mm ammo are two different loadings of the same calibre ammo. One is safe to use only in sporting chambers specifically marked .223 Remington. Either may be used in a chamber marked 5.56 MM Nato or some similar designation. The American Eagle ammo you mentioned is most likely the stuff suitable for use in sporting chambers whereas the XM193 is suitable only in 5.56 MM Nato chambers, but both may be used safely in 5.56 MM Nato chambers. I'm new to the world of AR's even though I'm retired from the Air Force and twice had to "qualify" on the M-16, the only two times I ever saw one in my career.

I've even taken a few rounds of what I have here and measured them with calipers. The XM193, marked as 5.56mm M193 Ball on the box, generally has a longer overall length than the other ammo I have labelled as .223 Remington. Since my "M4gery" has a 5.56 MM Nato chamber I don't worry about the ammo, though I would prefer to standardize, it just may have become more difficult to do that lately and I may have to purchase what I can when I can.

When I began to write this no one had yet posted a reply to you. I have written so much that this post will probably be number 4 or 5 on page 2. Anyway, have fun and don't worry about it. It all goes out the barrel pretty much the same.

American Eagle is a brand made by Federal. There is American Eagle XM193 in a black box. There is Federal XM193 in a brown box. All the XM193 are the same, just different boxes. Also, there is American Eagle 223 in a red box; it sometimes has Lake City brass but is loaded to lower velocities. Does that help?

I suggest reading through the existing threads, because they pretty much give this information.

All of the other respondents have given you great info. Simply put, the A/E .223 load is at least 200 fps slower than the 5.56mm loading. If you have a 5.56mm chamber, it's safe to shoot either one, but you'll probably have a slightly lower POI with the .223 load.

Hey. Ya I understood the differences between the .223 and 5.56 I was just trying to figure out if Lake City was the same as the brown box federal. As someone pointed out most of the lake city is .223 which I had not noticed. Thanks.

Lake City brown box XM193 is 5.56. The new American Eagle XM193C in the black box is also 5.56 and is the same as the lake city ammo in the brown box. The Federal American Eagle in the red box is .223.

Another difference is that the LC brass is good for at least 5 reloadings. The FC brass is good, maybe, for one.

From what my sales person at RSR has told me, what you have stated is true. The Federal XM193 is packaged in the military brown boxes and the XM193C is packaged in the Americam Eagle commercial black boxes but both are the same 5.56 m/m military loading. Also, the XM193 tracer rounds are not packaged in the military brown boxes but rather in the commercial AE black boxes. I have many thousand rounds of each of the military boxed versions as well as tracers. FR&G

A local dealer had Lake City 5.56 55gr for $189/500rds/boxed it's American EagleBlack Box XM193C The C stands for Commercial. Back then I just wanted a few box's to try but he would not break a box. Later as it sat there unsold he started putting box's of 20rds at $7.99 so I started picking up 200rds to try.

I noticed at the Wanenmacher's Arms Show dealers had it for $229/500rds. also noticed box's of 20rds marked $12.98.

The local dealer is now sold out I don't know what he sold it for but I am betting more then $198.
