A round stuck in an AR15 chamber

[Ggmac]

Penetrating oil isn't bad but I'd try a good bore copper remover , like wipeout , it will also dissolve brass , just a little slower than copper jacket material .

A good grease gun will only put 15,000 psi guess that isn't enough . lol Larry

I will work I have done it.

We have at our range a brass drop rod in different sizes . A R are famous for cases sticking . They have chambers all over the place on size I think one of the first had a good answer.
With a simple use of a drop rod would of solved the problem . Larry

Thanks, good info. Like the lathe plan, but no lathe available, the grease option sounds good but the barrel isn't threaded. I think the route that I will have to try is threading the case and pulled it like a case stuck in a die. I just hope my tap will reach with the barrel extension. I think I will have to run these into a 20 cal die...what cartridge is the neck sizer you use hogpatrol? A 223 bushing type neck only sizer?

Yes, a Redding Neck size die in .223 caliber, S type. Another option is to use a Redding Competition Neck sizing die. You can dial in as much of the neck as you desire. With this die, a modified shell holder isn't needed.

Redding's ad copy: Bold/Italic are mine.

The Redding Competition Bushing Neck Sizer Die is similar in concept to the Competition Seating Die, the cartridge case is completely supported and aligned with the sizing bushing before the sizing process begins. As the sizing process starts, the cartridge case remains supported in the tightly chambered, sliding sleeve as it moves upward. The resizing bushing self-centers on the case neck. The decapping rod is maintained in precise alignment by using the internal parts of the die as a linear support much like that of a firing pin. Meanwhile, the micrometer adjustment of the bushing position delivers precise control to the desired amount of neck length to be sized. Bushings and shellholders sold separately. Made in the USA.

After thinking about this, I doubt very much if that little part of the neck not being sized is the problem. SOME factory brand .223 full length sizing dies WILL NOT work for a .20 Practical AR. It's been a while but IIRC, I went through FOUR dies before I got one that properly sized Remington brass that would function without problems in my .20P AR. Having said that, I'd bet you have a stuck case because it did not squeeze the body down enough to fit your possibly tight chamber. Remember, .223 reamers have over a dozen iterations, from sloppy to tight and dies are all over the place. The .20P, maybe a few?

I think it's possible you have a bigger problem.

If it was just stuck on the neck, behind the bullet, you would have driven the bullet back into the case before the cleaning rod broke. unless you had a super crimp.

It is quite possible that the problem is the brass on your neck being too thick, and the chamber is wedging the neck tight against the bullet. Creating the super crimp.

It might be worth trying to find out if this is possible before going too much further.

I learne along time ago it could be this or something else wasn't a answer .
The best thing is find the problem and fix it .
The best way to find it is remove the barrel a check the cases to find where it is tight Many chambers requires a small base case
We used 5 different AR when testing. The tuners . With the small base dies we stoped sticking the cases . We also used a drop rod to get them out . Larry

Note to OP. When people are saying 'remove the bbl' they mean remove it from the upper rec so you have just the bbl itself to deal with. Just making sure you understand this.

PTG likes to sneak in the small base feature on 223 based wildcats. I have a 'standard' PTG 20P reamer that REQUIRES either new brass at .374" base diameter, or use a 223 small base body die. The reamer cuts a .375" base diameter, anything fired in a SAAMI .378" chamber won't fit. A std SAAMI dimension FL die WILL NOT size 'em down small enough.

Is the primer still in the case? If so, how the hell do you intend to drill and tap that round? BOOM!

 

[hogpatrol]

OP, any updates?

 

[DaveTooley]

Hope he's not in the hospital. The only safe way is to remove the barrel then remove the extension and go from there. I've used two guys and four screwdrivers before. A jewelers saw and cut the head off the case when there was no more rim to work with. It's a thinking mans problem.

 

[mac86951]

Tag. Good to know what to look out for when specing my 20p AR barrel.

 

[Hal]

Pull the barrel. Make a collet to fit the rim 360*, split it, put in a clamping screw and drill and tap the back end for a slide hammer.

Still here, just busy trying to get my poop in a hoop before heading out in the morning for a prairie dog shoot....w/o the 20P. I guess I will try to lite the fuse with a nail set. I shook all the powder out already. Pulling the extension off is not something I want to do.

I was in the same situation a few years ago with my 223 ar. A loaded round was stuck "real good".
Tried a couple of things at home, no good, took it to the local gun shop and the guy punched it out with a cleaning rod. He is an armorer and very knowledgeable about the ar.
My concern was the barrel, do I have to recrown, do I need a new one. Nope, it was all good, my ar still shoots very well as it did before.

One thing you need to carry is a brass drop rod . If you shoot a at with reloads Larry

 

[ebb]

Oh crap. How do you know that you got all the powder out? From what I understand from reading this is that the bullet is still in the chamber? And you are going to set off the primer with a nail set. Are you related to the guy that shot his steel toed boot thinking it was bullet proof? Please take this gun to some one that knows what he/her is doing before you kill yourself.

 

[remy3424]

Settle down, no powder left, weighed most of what shook out to know for sure. I might try a cleaning rod first so I don't have to deal with the primer. I have never set of a SRP, do know shotgun primers have a little behind them,I can't imagine there is too much with a SRP, I pop one in a rifle before I mess with try to pop this one.

Enough in it to send a 177 pellet thru a 1"x4 clen thru .
