[ARCHIVED THREAD] - XM193 Dents around the case neck

Posted: 10/1/2005 3:39:26 PM EDT

Are these ok to shoot?

For fun, yes. For serious defense work, I'd stay away from them. Those don't look like oil dents, but more like dents from abuse.

Somebody else posted about having some rough looking XM193 with dents but I can't find the thread. I plan on burning them at the range, so no danger of overpressure?

They won't be over pressure due to those small dents.

If you have any issues at all, it will be a chambering problem. The dents may have made the cases slightly out of round, and they may be a tight fit in the chamber.

Thanks, your comments and others like it in a similiar thread a few months ago have put my fears to rest. FYI, here's the thread ar15.com/forums/topic.html?b=3&f=16&t=244776

Normal. No biggee.

Yes. They'd go bang. It's just that they've probably been chambered before, and the charging handle was made to "follow" the bolt carrier when it returned to battery.

I thought sealed XM193 is factory new ammo?

It is. Ignore that foolish reply. Chambering a round will not creat those kind of dents anyway.

I'm surprised at the amount of misinformation concerning all things AR. Thanks fellas

Drop them in a case gauge... you do have one, right ?... If they fit the gauge and check out, shoot them. The 45,000+psi chamber pressure inside the case will fire form them dents right out smooth as the chamber, never know the difference when you look at them when you pick them up and look.

I drop all my ammo, that avoid an embarrasing stoppage while out blasting with company, or shooting a pistol/rifle match.

Huh?

You use the case gauge to visually verify that the external dimensions of the case is in spec so that the cartridge will likely fit the chamber as intended.

Oversize rounds will not fit the gauge, so they will not fit the chamber,,,, right.. I drop all my ammo to avoid embarrassment, or keep from having a PIA stoppage and cutting the day short, or a DNF..

It is taking me a few minutes to get pic from camera and upload to host .......

Some of the rounds of M855 look like that when pulled out of the bandos on strippers from ammo for Gov't use. . Nothing to worry about.

Ever tried ejecting a round manually, not pulling the charging handle all the way and releasing the bolt slowly? Your bolt will definitely not "catch" the next round. Instead of engaging the base of the case, the bolt will in fact slide along the case as the bullet tries to leave the mag. Give it a try, you'll know what I mean.

And it's not a foolish reply.

I beleive he was referring to the comment about XM193 from a sealed case being previously chambered. Not that chambering wont' cause the dent.

Nope, read the post. Real deal XM193 and others have said it's normal(see ammo oracle tacked here).

I have inspected a shit load of lot 102

Widener's, listed in the ammo price list. Somebody else was saying recent production was looking kinda ugly. As long as it's safe to shoot, I'm good. arfcom veterans are saying it's not unusual.

Okay,
Lot 103-105
Anybody seen it yet???

Hey SBR7, where would one find a gauge like that one for 5.56 ?

Uahhhh since there are NO external case dimension differences between 5.56 and .223, you can use ANY case gauge on the market for the cartridge.

Mine is a LE Wilson, bought it at Midway some 15+ yr ago... been a very use tool since I bought it.

I currently keep a 223, 30-06, 8x57, 9x19, 38 Super, and 40 S&W gauges on hand. The 40 gauge is really handy when it come to the 40 brass, as some of them Glocks have case bulge, and the 40 case will fit either way in the gauge if it is good. I had to really keep an eye on 38 Super, I would usually bulk resize, drop, load, and drop again, saved a lot of "DNF" there.
