The XM193J is a great cartridge for those who want caseloads of 5.56x45 but know that the stripper clips add significant value to their particular shooting routine. The same great federal American Eagle value pricing and component consistency, as well as the proven reliability and accuracy, this is the XM193 you’ve come to know and love from American Eagle, but with the added bonus of stripper clips.

The 55 grain projectile is a very versatile bullet and works in just about every barrel twist within reason, offering great flat shooting trajectories and a clear cut advantage for smaller game or when you want fast, responsive shooting at short to moderate distances. Packages 30 boxes to the case; with 3 stripper clips loaded with 10 rounds each in a box, you get 900 rounds of easy to load, easy to love American Eagle ammunition that performs exceptionally in the AR platform and beyond.

Depending on the case purchase, the stripper clip guides may not be included with this case load. The factory has discontinued the inclusion of the guides, but the stripper clips are still very functional and you can fid guides elsewhere on the BulkAmmo website.

A: Your rifle will be accurate with any 5.56x45 ammo. The 1/7 twist rate for the .224 diameter bore will stabilize any bullet that can be safely loaded to magazine length.

Posted On: 10/21/2011 By: August

A: The stripper clips are extremely light, and will not corrode if the ammo is stored properly. If the ammo is stored improperly, corrosion on the stripper clips will be of minor concern compared to the potential for deterioration of the ammunition.

Posted On: 10/21/2011 By: Scott

A: No, the guides do not come with the product. We offer 3-packs of the stripper clip guides under the "Shooter's Ridge" brand.

Posted On: 10/21/2011 By: Owen

A: No, stripper clip guides are not included, but we do offer three AR-15 magazine stripper clip guides for a very reasonable price.

Posted On: 10/21/2011 By: jerry

A: Using a stripper clip guide, magazines can be loaded very quickly, just by pushing on the ammo at the bottom of the case. 10 rounds can be loaded into a magazine in half a second or less.

A: No, those restrictions are only on hunting in areas where the California Condor is present. You are still able to buy and shoot lead core ammunition in California outside those areas.

A: This 5.56 ammo will have approximately the same accuracy as the Federal value packs of 100 rounds.

Posted On: 10/21/2011 By: glockman1727ak47

A: The stripper clips are very durable. They're made from parkerized steel and brass. We offer a three pack of AR-15 magazine stripper clip guides separately.

Posted On: 10/19/2011 By: Jeremy Dawkins

A: If you have access to .224" diameter tracer bullets and have the requisite skill and knowledge to safely reload ammunition, then yes, you can use the fired cases from this ammo to make tracer rounds.

Posted On: 10/18/2011 By: Quicksaber

A: Yes, the stripper clips are new manufacture.

Posted On: 10/13/2011 By: Jacob

A: Yes, both XM193 and XM855 are loaded with Lake City brass.

Posted On: 10/11/2011 By: West

A: The difference is primarily in the designation - XM193 was not sold to the government, while M193 was. Both M855 and M193 will work fine in 1/9 twist barrels.

Posted On: 10/11/2011 By: Aaron

A: 5.56mm ammo will offer higher velocities, greater terminal performance, greater barrier penetration, and less wind drift and drop at long distance than .223 Rem. .223 Rem might have slightly less recoil and muzzle flash.

Posted On: 10/10/2011 By: Jeff

A: Well, if you're looking for accurate ammo, check out ammo that is described as "match" by the manufacturer. If you want cheap ammo, then pretty much anything will do. If you want ammo that's reliable under harsh conditions and designed for military use, buy military surplus or contract overrun ammo. Almost anything with a brass case can be reloaded. It all depends on what you want to do with the ammo.

Posted On: 10/10/2011 By: Steve

A: The Dillon Super Swager is very popular for this purpose - it is efficient and effective.

A: Federal uses all new brass for this XM193 ammunition.

Posted On: 9/30/2011 By: Mark

A: This is true. The chamber of a .223 rifle has a shorter leade and .223 ammo is loaded to lower pressures when compared to 5.56 ammo and pressures. When 5.56 ammo is used in a .223 chamber, pressures exceed not only standard .223 limits, but also 5.56 limits, which is a dangerous and undesirable situation.

Posted On: 9/30/2011 By: Anonymous

A: This ammunition is specifically designed for use in AR-15 platform weapons.

Posted On: 9/29/2011 By: steve

A: It is not advisable to fire 5.56 ammo through a .223 Rem chambered rifle, as excessive pressures can result.

A: This Federal ammunition features boxer primed, brass cases, which can be used for reloading. The primers are crimped for reliability in semi-automatic firearms, which poses a minor difficulty to reloaders, but does not prevent them from being reloaded. All that needs to be done is for the primer to be removed, and a special tool used to press the edges of the primer pocket back to their normal, pre-crimped position. Then, the cases can be used for reloading just like any other.

Posted On: 9/29/2011 By: Jonathan

A: Because this Federal XM193 ammunition was loaded on a military production line, the primers are crimped.

Posted On: 9/29/2011 By: Andy Weiser

A: During manufacturing, the cartridge cases are "annealed." This process makes the brass easier to work and less brittle. Because of the temperatures involved, discoloration is common, but the process results in higher quality brass.

Posted On: 9/29/2011 By: Gary

A: The XM193 ammo is fundamentally the same as the M193 that was once used by the military. Federal states that the X means that it was intended for government sale but was instead sold to civilians.

Posted On: 9/28/2011 By: Ted

A: As stated in the description, this ammo comes on 10rd stripper clips in boxes of 30 rounds each.

Posted On: 9/28/2011 By: ARSHOOTER

A: At this time, we ship the ammo as we receive it from the manufacturer.

Posted On: 9/28/2011 By: Matt

A: It is not recommended to fire 5.56mm pressure ammunition in a .223 rifle. Federal does manufacture ammunition with a 55gr projectile loaded to .223 pressures.

Posted On: 9/28/2011 By: Anonymous

A: We do not currently offer bandoliers.

Posted On: 9/28/2011 By: Matt

A: Both can be quick methods of loading magazines, but both require practice to be extremely fast. Stripper clips are probably easier to get the hang of.

Posted On: 9/27/2011 By: Tom

A: 55 grain 5.56 bullets will perform equally well in either a 1/8 or 1/9 twist barrel.

Posted On: 9/27/2011 By: Rob

A: Federal states that the "X" means that the ammo was not sold to the government, and that this does not mean that the ammo was from a reject lot.

Posted On: 9/27/2011 By: Jack H

A: The stripper clips are the length of ten rounds standing side by side - about 4". Approximately six will fit in a single 30 round mag pouch, though some will stick out the top of the pouch.

Posted On: 9/27/2011 By: James

A: There are no indications that XM193 will not continue to be available in the future.

Posted On: 9/27/2011 By: Dallas

A: "Civilian" ammo might not be loaded to 5.56 pressures - it would be identified as .223 Remington, in that example.

Posted On: 8/25/2011 By: AR-Man

A: Much of Federal American Eagle's 5.56x45mm ammunition is manufactured at the Lake City Army Ammunition Plant which is currently operated by ATK, the owner of Federal Ammunition. This XM193 ammo is manufactured on a line at the Lake City plant designed to meet military specifications and one of those specifications is that the brass needs to have visual proof that it has been annealed. During the process of manufacturing new brass casings, the brass is being reshaped through a series of presses to form its final shape. This process of necking the new brass leaves it naturally brittle at the neck of the case. To re-strengthen the brass after it has undergone this re-sizing, the brass is run through an annealing process which essentially reheats the brass by running it through a series of flame torches. This process of running the brass through a series of flames makes the brass strong in its new molecular shape. All necked rifle brass, both commercial and military, goes through this annealing process. Commercial brass designed for civilians is re-cleaned after it has been annealed for cosmetic purposes. The military however places a stronger emphasis on quality over cosmetic appearance and as such requires that the evidence of the annealing process be left on the brass for visual inspection.
