Either you did not take the time to break out a Chamber brush with CLP to fully clean out the storage grease and it's embedded debris from the the barrel before you when to fire it, or you have a gas problem going on.


When you went to first shoot the new barrel, did you install just a single round into a mag, charge and fire that single round with the empty mag still in the rifle to see if the rig was full stroking/ locking the bolt back on the bolt catch?????


If not, the go do that since we first need to know if the rig is at least full stroking or not.

Sounds like most of the problem is a dirty chamber, so cleaning that should help out a lot.

But still may be over gassed a tad (read op has already confirmed that the rifle is full stroking), so may want to add a #60 O-ring (about a dime at any hardware store) around the extractor spring to tension the extractor up a tad for break in.

If too tight of a head space was a problem, then you would have never gotten the bolt to lock back to begin with.


Also, you do have a lot post count, so let me state this, Hoppes is about the worst to use to clean and lube the auto loader.  BreakfreeCLP can be used to not only lube the upper bearing areas/the gun, but to clean 99% of it as well.  The barrel bore will need something a clean Copper out quickly, and here, something like Sweets solvent works great without having to do a lot of brush scrubbing.


So, B/C get pulled and a fresh shot of CLP to let sit while you are clean the rest,

Bore gets cleaned with Sweets first, then go after the chamber with CLP and a chamber brush, followed by running dry patches through the chamber and bore until they come out dry.   Now go back to the B/C and the rest of the rifle to clean and relube those parts. As for lubing the upper bearing areas, wet the B/C inside and out, put it in the rifle still wet, then dry cycle the action a few times to migrate CLP off the B/C to the upper bearing areas.    If in a few hundred rounds you state to have jamming problems again, pull the B/C, give it another coat inside and out, put it back in the action with a few dry cycles, and go on shooting.

CLP is not only a lube, but has a very good cleaning agent in it, and will dissolve the fouling before it has a change to build up and choke out the rig.

The stuck casing could be caused by many things like maintenance, ammunition, and timing issues.  Have you tried the rifle with any other types of ammunition?  Clean the chamber thoroughly as already mentioned.  Have you changed out anything like the stock, action spring (buffer spring), buffer, bolt or bolt carrier?
