Federal AE 5.7x28 Ammunition Issue

[twarr1]

I have always used FN or handloads in my Ruger 57. Recently I bought a few boxes of Federal American Eagle AE5728A 40 grain. The very first one did not chamber. I dropped the magazine, locked the slide and raised the muzzle to attempt to remove the round. The cartridge case fell out, followed by propellant and then the bullet, I unloaded the magazine, put the rounds back in the box and put the pistol away, since it was now littered with loose powder.
I wrote Federal, curious to see their response.
Has anyone else had similar issues?

Do your handloads still chamber as they used t?. Dumb question on my part, but is the throat and chamber clean?

I would contact Federal to let them know.

Back when I had a 5.7 AR upper, all I ran was Federal American Eagle and it always worked great and was accurate too.

Try the plunk test

@Trent documented a problem with Federal 5.7x28 ammo setback many years ago. It seems they don't glue/epoxy/whatever their bullets into the case but FN does. Trent's research convinced me to always buy FN ammo for my gun. I passed the same advice on to the guy I sold my gun to.

Federal responded, said they don’t have replacements but they’ll refund what I paid for the ammunition. They want it back.
Fair enough.

Had the same thing happen to me several years ago with the first round fired out of my NIB FN 5.7. The moderator (and P-90 owner) of the firearm forum that I frequented at the time informed me then that bullet/case separation was an inherent problem with American Eagle 5.7 x 28 ammunition. Apparently it still is.

Never a problem with FN (Fiocchi) ammunition. Around that same time CDNN Sports had a sale on FN 5.7 ammunition and I bought 1500 rounds at .23 cents per.
