alright guys I got a dpms style .308 that I put together from parts. I only have maybe 50 rounds through it.
Tonight I was trying to develop a load for it. and it was functioning fine.
Now a hot load is not the problem as the case jammed going in to the chamber. It was just short of fully closing and for the life of me I can't get it out I bent the charging handle and ripped the edge off the rim of the case and ruined 2 cleaning rods trying to hammer the round out from the muzzle. and it still wont come out....
The bolt did accidentally close all the way when I was slamming the but stock on the ground trying to get it unjammed so I was able to at least get the upper off the lower and the bcg out.

any ideas?

Re: dpms .308 stuck case need help

This is a live round, I take it? I wouldn't recco pounding on it anymore if you value your body parts.

Get some Kroil (or other thin penetrating oil), soak the bottom of the case, and then point the barrel up, pour some oil in and let it sit for a few days. I'm sure you've driven the bullet into the case with the pounding, so hopefully the oil will kill the powder and primer.

Get a bare bullet (no case, JUST a bullet).

Fill the barrel (pointing up) to the very top with oil.

Put it in a freezer overnight.

Put the bullet (Point first) in the end of the barrel and smack it with a brass hammer (make sure the barrel is still full of oil).

The hydraulic force should knock the case out of the chamber, 99% of the time it will.

IF it doesn't, beat the bullet in good, to seal it off.

Get a heat gun and heat the chamber area good and hot and beat another bullet in on top of the first one.

If that don't do it, send it to a gunsmith that can drill it out.

When done, knock the bullet out the end with a good rod.


You realize you're going to have to use some good full length sizing dies from now on, right?

Re: dpms .308 stuck case need help

I have one of the DPMS 308's as well, it appears the chambers are tight, that is why when I do reloads for that I use a small base die just to make sure a round does not get stuck in it. good luck with it Nathan! the good thing is they are accurate, so it makes it worth the extra hassle.

Like said already, small base dies always! I am not a big fan of Hornady dies, but no matter which brand they need to be small base!(I prefer Redding)

I know guy's that got away with full length, till they got brass that was fired out of another chamber that was large enough to not make the transition all the way into the chamber. With new brass and brass fired out of the same chamber, it doesn't seem to be a problem, ("USUALLY")but there is always the chance. The first and most important thing in my SASS is it feeds and fire's!!! The second most important thing is accuracy! Reliability! reliability! reliability!http://www.snipershide.com/forum/images/icons/default/thumbs_up.gif

Thats what I was thinking, so what is it pulls the rim while ejecting you don't have a live round stuck in the chamber. I always use FL dies and never have had any issue at all.

sudnrush, I agree with Scottmilk9 but please brother, dont be beatin on a live round with a rod or anything else. If the BCG is in battery and you decide to pull the trigger, do it with a string pulling the trigger and from the opposite side of a large oak tree after the rifle's been tied to it and dont be surprised if it blows up. Otherwise, take it to a pro or just remove the barrel and throw the SOB away! Damn, its not worth loosing life or limb over. Its just a f'n barrel for cryin out loud, they're wear items at best.

okie

If you do not do them in sequence it will happen that way. I had a match chambered 308 that I took a set of lock jawed pliers and pulled half the rim off trying to get the loaded road out. Doing the method I described worked perfectly. You can easily break a charging, if you do not do them in sequence.

Definately don't pull the trigger at this point. Sudnrush stated that he ruined two cleaning rods trying to hammer it out from the muzzle. The bullet is probably shoved deep into the case at this point or jammed badly at the neck and discharging the round will most likely result in a catastrophic ka-booom.

Re: dpms .308 stuck case need help

Speculating as to why the round is stuck....on the off chance the brass has been fired several times, there is the possibility that this piece may have become thin in the shoulder area and when the bullet was pressed into the case, the shoulder buckled enough to jam the shoulder of the case into the chamber wall.

Assuming the case is not completely seated into the chamber, I would explore the possibility of splitting the upper and lower and removing the barrel. With the barrel loose from the upper, the back end of the case could be gripped with pliers and the round removed from the chamber. Barring positive results, the barrel could be placed in a press (hydraulic or arbor) and a solid steel rod run down the bore to press the round out of the chamber.

Re: dpms .308 stuck case need help

well guys good news I got the darn thing out! Thanks for all the help!
Since the bolt did go in to battery and I figured the bullet couldn't have gone to far in to the case the powder would have maybe stopped it. and it was a light load as I was just starting load development. I went a head and just fired the round it was no problem. I did do it from a distance with a string to be safe. The primer showed there was a little bit of pressure but nothing excessive. Pry still Not the best way I could have done it as some of you said but it worked out okay.

Just some clarification I did slam the butt to the ground while pulling the charging handle even tried using my foot to push down on the charging handle while slamming the butt on the ground I just couldn't get enough leverage on the handle while keeping the muzzle pointed in a safe direction also I doubt that would have worked. I bent the charging handle by hitting it with a brass hammer it still works looks like crap! I only got the bolt to open when the extractor tore the rim off the case when I used a brass punch to pry between the front of the bolt carrier and the ejection port of the upper.

Now reasons it probably got stuck I was using brass that had been fired in my rem 700 then full length resized in the hornady dies. sounds like those are both bad things to do with these guns.
so I will either get a small base die like was recommended or just use commercial ammo.

sorry for the long post just thought Id let everyone know what I did to fix it and why it may have happened for future reference should it happen to some one else or just as a guide of what not to do haha

Thanks again,
Nathan

It talks about several fatalities from beating on loaded rounds!!!! </div></div>

I read that earlier today I kinda thought someone would post a link to it. I will do things different should I have another problem

Thanks,

Consider yourself lucky.
You easily could have been hurt.
I know that it seems impossible, but what you did has a bad history.

I'm glad all is well.
Always check resized cases (empty) in your chamber when you start resizing to make sure they fit properly, and adjust accordingly.
