The damn round was jammed in there like crazy.
Looks to me that it was damaged before it was chambered. What brand was it?
Wow, sure looks like it! Good to hear you got it out without having to buy an air compressor.
If you still have the rifle apart, or even if you have to take it apart again, take a good flashlight and inspect the chamber. Make sure that there is not anything left behind in there or the bore. Make sure the chamber looks symetrical and not mishappen.
The problem here was almost certainly the ammo - I am thinking a loose bullet that wedged itself into the chamber at an angle - but I would still inspect the chamber and bore to make sure they look OK.
Are there marks on the bullet from the rifling? Just wondering if the bullet engaged and got stuck on the lands. Does not look like it from the photo, though.
I would check the ejector just to eliminate that issue..The air compressor was sitting there as my backup, along with some tape and putty to get a seal. I checked the barrel while giving it a good cleaning and it looked good (at least to my inexperienced eye). There was some marks on the bullet but I'm not sure how it would look like from the rifling. The bullet is also sitting on a bit of an angle (can't see it in the picture) so that could have contributed. All in all it was probably just a really crummy round.
On a related note I shot about 100 rounds from the same box today and got two FTE's but no more jams.
