Del-Ton AR-15 question

I traded a MOA Specialty Pistol for this gun a while back and I'm having issues with it. Every once and a while when a round is chambered the bolt will not open. The only way to release the round and bolt is to remove the barrel. This only seems to happen with reloaded rounds but I have shot few factory rounds out of the gun, maybe 60 rounds.

I thought I fixed the problem by scrubbing the chamber real good but today it happened again without firing it. I simply chambered a round and the bolt refused to open. It almost seems like the bolt face is not rotating fast enough???

This is the first and only AR that I have reloaded for and It may be my error butmy other semi autos have no issues with my reloading. When I reload I first re-size and de-prime my spent brass with a SB FL sizer die. I than tumble it, clean the primer pocket, debur the flash hole if necessary, trim to specified length according to my Hornady manual if necessary, and chamfer the inside and outside of the bullet neck.

I'm not sure what the deal is??? Either I'm doing something wrong or the gun is??? Could I be leaving lube on the cases??? Opinions on Del-Ton???

Thanks
Ryan

Re: Del-Ton AR-15 question

Have you measured several loaded rounds yet? Base to ogive and the diameter of the base , neck dia. etc. Try chambering resized brass only . If all that checks out then I would move on to the chamber but more than likely the dies need to to be adjusted or your are using brass that was fired in a larger chamber and the brass is springing back after you size it. I had that trouble also .Did you say Factory loads cycle fine ?

Re: Del-Ton AR-15 question

Chambering resized brass has the same results only every piece of brass jammed. I measured 7 loaded rounds and everything came to be within .002" except the OAL which deviated .005", but that length didn't seem to reflect weather or not the issue would persist. All the brass I'm using was factory ammo shot out of my gun that I'm reloading.

I believe I had this problem the first time with factory ammo (can't remember for sure). Other than that it has all been reloaded ammo.

Thanks

Re: Del-Ton AR-15 question

So reloaded ammo jams, and your trimming the cases? Does it jam so bad you have to shotgun the weapon to cycle the bolt? Seams to me like you have a bad bur in the chamber or your extractor is shot. I know this is a lot to ask but can you make a video? If its jammed up hard its a different issue than its just not extracting rounds.

What are you using for lube and how much? AR's are like porn stars you have to lube them and lube them a lot!

Re: Del-Ton AR-15 question

is it 223 or 5.56?

223 is a shorter chamber, no?

Is your re-sizeing die set to high in the press?

Re: Del-Ton AR-15 question

I'm a little busy to post a video this weekend but I did notice a decant scratch going down the casings and even the bullet it self. I tried to clean the chamber with a wire brush that fits in the chamber, the neck of the chamber and the star chamber, and than I scrubbed it with solvent.

I can not see any burs inside the chamber with the naked eye but I'm no gunsmith. After that I put it all back together and and cycled some rounds through it. The first one was smooth and the second one jammed. I have found that I can separate the lower from the upper and pry the bolt carrier open with a screwdriver pushing toward the front of the barrel without too much pressure.

Thanks
Ryan

I have it in mind that you forward assist may be the culprit here.
