I have had luck with KROIL OIL and Doll Rods, made of hard wood or brass. Never had multiples stuck.

I decided to pull off the barrel to make it easier just incase I attempted to melt out the bullets or what not.
There is obvious bulging under the gas block because I had to beat it to get it to move. In fact I'm going to have to cut off the gas block. I had to cut the gas tube as well in order to get the barrel nut off.

So the barrel is toast. thanks for all that offered suggestions. I'll have to get a new barrel when I have more money.

I think I may mount the barrel in my reloading room as a reminder :grin:

You may be able to have someone salvage it and make a real short sbr:D I bet spook would be willing to try if he has nothing better to do. How about a 4" 300w ar upper lol :uzi2:

I did the same thing shooting subs out of a .223 except I shot a full power load afterward and it was obvious what happened as the crack and bulge blew out in front of the gas block. Luckily my suppressor and I weren't damaged.

I had it cut to 10.5" and it worked fine as a shorty, but my overconfidence cost me a great shooting barrel.

It sucks, but subsonic shooting has this as a risk. If you don't see the impact, take the time to dismantle the upper and check the barrel. It is an expensive mistake and it only takes a minute to check. Also, give it a few seconds before cracking it open as hangfires can cause just as much damage if opened prematurely!

I learned the hard way too!

when I work up a load I carry a one piece cleaning rod, after each shot (if I dont see the impact) I lock open the bolt and slide the rod down the muzzle making sure the bore is clear. Its faster than breaking down upper to look through bore........

As bad as it is if you want it to make a mice display/reminder mill a little less then 1/2 the barrel away were the bullets are stuck. It looks realy good. I have done this to a couple of guns for people.

6 grains of 2400 with a 220 grain bullet is almost certainly what got you in trouble. I use 8.0 grains of 2400 behind 208gr Amaxs and thety are subsonic.

I think this is why using a chronograph is so important developing subsonic loads. If the report isn't as quiet as you expect and you keep going lighter it can lead to stuck bullets pretty easily.

do this& post pictures:grin:

thenodnarb, Is there any sign that the carrier key impacted the rear of the receiver?
