bullet forced into case?

[phillychoppin]

Hey guys,

I'm new to long guns and just picked up my AR this morning. I also got a box of cheap Finocchi .223 ammo to play with.

When I got home I read through the instruction manual and started toying with chambering some rounds and cycling the extractor. Everything was working fine until I had a failure to extract.

I opened the bolt and saw the round in the chamber. When I released the bolt I noticed that it was not all the way closed so I tapped the assist assembly, which closed the bolt then cycled the bolt again and the round popped out.

When I looked at the round it was obvious that the bullet was pushed a bit back into the case and I could smell a bit of powder.

I put that round aside and cycled through several more chamberings and extractions with no issues.

Have you guys ever seen this? Did I do something wrong or does this just happen sometimes? Could it just be cheap ammo or is something wrong with my rifle?

Thanks,
PC

There are a number of reasons why that could happen. Usualy it is caused by the bullet catching the barrel extension when feeding. HP ammo tends to do it more often esspecialy if your rifle doesn't have the M4 feed ramps. I am not familier with Fiochi ammo's crimp either, if the crimp is lite or not at all then they will set back easier.

I doubt there is anything wrong with the rifle. It is probably just the ammo.



JMHO,

+1 to what warner said, it could have been the angle that the bolt picked up the cartridge at and it snagged a bit on the feed ramps. A light crimp could also just not hold the bullet securely enough, or a combination of the two. I wouldn't consider Fiochi cheap ammunition, it was probably just a round that slipped past quality control, although I'm not familiar with their crimp either. There is also the chance that the overall length of the cartridge was slightly out of spec and that could be another reason why it might have snagged or drug across the feed ramp. I wouldn't worry too much, just glad that you caught it. Best of luck to you
