Shooting WWB 45ACP 230 grain FMJ.

Shot fired, case ejected, next round fails to chamber and gets crunched by the slide. I've had this happen one time on each of my last two range visits (Mon and Tue). In both cases the round has a visible bite mark from the action. The first time the round was 2/3 of the way into the chamber and would not load even after I put it back through the mag (with the RO's supervision). The second time (today) the round was nearly vertical in the action and was not even close to properly chambering.

The WWB appears to dirty up the gun pretty quickly, I'm thinking that my feed ramp was just fouled enough to retard the chambering of the next round.

Any ideas?

The two FTF's you describe sound unrelated. The bullet not fully chambering on two tries sounds like an ammunition issue(out of spec), and the bullet stove-piping was probably a fluke or at worst magazine related.

2 FTFs is nothing to brush off as normal and that is something definitely worth looking at immediately if the XD is your personal defense carry weapon.

That certainly is some major fouling on the feed ramps part if rounds seemed retard and were misloaded. I'm guessing limp wristing is to blame as well(try having people watch you shoot) although using different ammunition may yield better results.

Hopefully the malfunctions were something minor like the magazine feed lips being bent out of shape, those can be reformed. Try to avoid improper storage and treatment of your magazines because they are obviously a vital part of the weapon. It's funny how they are crafted of metal but bend so easily

I would check the bbl. breach to see if Ammo. seated without any sign of binding or tightness.

Isn't a stove-pipe when an empty case jams in the action?

This is a live round crunched in the action. And I can't see how they're unrelated, they're identical except that the first round made it in the chamber, the second did not.

It's not the magazines, they are not bent or damaged in any way and have been stored and handled gingerly.

Yes you are correct, I misunderstood your description. My opologies!

RicochetJim · 03-29-2006, 07:37 AM

Would it look like this? I call it the three-point jam. It has been known to happen on occasion. Notice crease in cartridge case.

farmer · 03-29-2006, 07:39 AM

Do you have a second magazine, just to rule it out?

fyeguy · 03-29-2006, 07:39 AM

RicochetJim, that's exactly it! That's how the first one looked, the second one was nearly the same, except the round didn't make it into the chamber, it went straight up.

What's the cause? Anything I can do to prevent it?

RicochetJim · 03-29-2006, 07:52 AM

In the flurry of occurrences discussed on the Forum some time back, the suggested fix was to polish/blend the top edge of the feed ramp.

I had a few occurences myself (in my .40 not my 9mm) and thought it was the WWB ammo. However, I merely kept shooting and it went away. So, I'd suggest blast another couple of hundred rounds and see. Simple use may slightly round (or smooth) the top edge of the feed ramp.
