I was considering getting some. It box (online) says reloadable brass cased. How good is it? Is the primer crimped?
As kind of an aside, could someone point me in the right direciont to a site or thread about reloading using 5.56 cases. Like what extra tools and such you need.
Most Federal brass is crimped, so I would imagine the American Eagle is too. You just need an RCBS decrimp tool to take care of it the one time. That's the only special tool you'll need. Other than that, it will reload just like any other brass. I've found that once I trim .223 brass to length, it does not seem to grow like the rounds I shoot from my M1 Garand. Must be something about my AR chamber. It's a RRA NMA2. Not sure how your's will do; guess it depends on the rifle and chamber.
Federal operates the Lake City plant for the DoD. I believe much of the Fed AE stuff is made on the same equiptment to the same specs. In essence it is LC M-193 with a Federal headstamp. Remove the crimp with a swager or chamfering tool, trim and load as if it were 5.56mm
Look to see if the headstamp is LC or FC. Both are reloadable, FC has a spotty reputation although my experience has been good. There is American Eagle-marked ammo made in the same plant and specs as XM-193 (and so has LC brass), and AE made to 223 specs elsewhere.
If it is LC, assume it must be decrimped, by swage of reamer, as was said.
