Do not use a blank cartridge.
Blanks contain very fast burning powder. The US military used EC blank powder for nearly 100 years. EC blank powder was also used in fragmentation hand grenades.

And P.O. Ackley welded the muzzle/barrel on a Japanese rifle, chambered a round, pulled the trigger and NOTHING! Forget the rifle, I want the cases. A shooter near Houston,TX failed to remove a laser bore sighting tool, chambered a round, pulled the trigger and turned the barrel into something that resembled decorations on top of the Manhattan Bridge, or the top of a river boat smoke stack, the barrel shredded. The barrel shredded at the weakest point, the muzzle.
So, where is the obstruction? Then there is that part where I say I am a big fan of the running start, I do not want my bullet jammed into the rifling before pressure builds, I want the bullet to have a chance to get out of the way, again, time is a factor in all my rifles, others choose to claim exemptions, like Sargent's, Sargent's have exemptions.
Scary! Jam a bullet into the barrel, lock it with a stick, chamber a round, pull the trigger, then pick up all the little pieces, time is a factor, I want my bullets to have a running start.

From the bullet end pour mercury down the barrel let it sit over nite the mercury will disolve the lead. just pour it back out into a pan the lead will seperate from the mercury.

works on jacketed bullets to it just leaves a copper shell you have to get out.

Mercury and its compounds are extremely dangerous.
While it will amalgamate with the lead and copper and allow the bullet or what's left of it to be easily removed, there are too many other issues involved.
I handled mercury and amalgams on a daily basis during mining operations.
And ALWAYS with every care and protection to avoid exposure.
I'm not even sure how easy it is to obtain anymore, but I would advise anyone considering trying to use it to spend some time reading about the dangers involved and proper handling.

If you spill any mercury in your house, you now have a Haz-Mat clean-up site on your hands instead of a home!!
Don't do it!

Hg is not extremely dangerous...
it is a poison, a heavy metal, largely insoluble in water and a liquid at room temp. You should not drink it (it was given for stomach trouble in the 1800's), if you handle it you should use all the precautions you would use handling any other poison. It should not be heated to boiling unless you do it in a very controlled environment, but that doesn't make it extremely dangerous. It will not jump up and kill you anymore than a loaded gun will. Closing down a high school because someone broke a mercury thermometer is perhaps one of the most foolish manifestations of our PC world. I too handled mercury on a daily basis while panning for gold, never got sick, don't have it in my system, am (so far) living to a ripe old age. And we made sure we recovered every milligram of it, 'cause it's so damn expensive! But I also use MEK in my shop (you know, the stuff referred to in this forum as "Cancer in a can!)"...
Just my opinion, YMMV!

Beg to differ. It is because of its toxicity. Granted things dealing with minute amounts can get out of control, just like the foolishness over asbestos.
Over 60 years ago my Dad had bottles of mercury around and us kids played with it all the time, no it doesn't jump up and knock you dead.
But, I will still tell everyone, if you don't know how to handle it, stay away from it!
I know several assayers who still take chelating agents to try and remove mercury accumulations from their bodies. It does not pass out of the body, but rather will continue to build up depending on exposure.
It's dangerous, pure and simple.

Not to highjack the thread, but...
"When considering the hazards of mercury, soluble mercury compounds and metallic mercury are very different. Mercury can enter the body through the lungs, through the skin, and via the digestive system. The absorption of mercury vapor by the lungs is an efficient process, but it is difficult to acquire dangerous amounts of metallic mercury by the other routes. Ingestion of soluble mercury compounds produces acute mercury poisoning, but is very easy to avoid and rare. Usually, mistaking mercuric chloride pills for something harmless is the cause (see below). The kidneys contain a protein, metallothionein, that binds mercury tightly until it is excreted. Mercury in the blood has a half-life of only three days, but tissue mercury has a half-life of perhaps 90 days. Small amounts of mercury, therefore, are efficiently excreted and cause no harm. This information is from the Handbook of Laboratory Safety (2000)." from the web site of Dr.J.B.Calvert, U. of Denver
And I never said it wasn't dangerous, I said it wasn't extremely dangerous. One of the precursors to the malignancy we now call PC was the inability to differentiate between real and apparent danger (i.e. "Assault" weapons). I think that the term extremely dangerous should be reserved for things that are extremely dangerous, like a women scorned. Again, just my opinion, YMMV.

Hi, F. Guffey,
Do you have a reference to that Ackley experiment? I am aware of an experiment by Hatcher in which he blocked the barrel of an M1903 rifle so the bullet could not move, and fired the rifle. Nothing happened. When the bolt was unlocked, there was a loud pop and the bolt flew open.
But there is a lot of difference between preventing the bullet from moving and stopping it once it is moving. In the first instance, there is no kinetic energy to deal with, since the bullet does not move.* In the cases where the bullet is moving and there is a massive energy dump, the barrel will always be bulged or split.
*Note that in a recoil operated gun, like an M1911 pistol, if the bullet is prevented from moving there is no recoil; the slide/breechblock will not move and the gun will not function.

No, the dowel can just crack along a diagonal grain line and for enough of a wedge shape to expand under hammer blows.
Sqiib rods are not just dead soft brass rods.
They should be at least 1/2 hard or better to keep THEM from mushrooming out.
A dead blow hammer and LOTS of small taps will do the job.
Save the Herculean blows for breaking up rocks.

mercury was used in fillings in your mouth HOLY CRAP among other things. Use commen sense for one thing do it outside dont play with it like we did when we were kids lol. Use rubber gloves the amount you will be using should be about 1/2 oz Use it then take it to a haz mad drop off usually the fire dept. We have probibly removed 50 bullets in 20 years that way I personally would not do it any other way because I have tried most of them and they all suck. But I do have 6 toes on one foot.

mercury
I remember playing with mercury as a kid. Nobody thought it was a big deal. I used to go arm-deep in a vat of PD680 every day too..and my lifespan will almost certainly be shortened as a result.
I'm not an eco-alarmist, but I am a realist. Playing with trich, mercury or any number of chemicals thought to be harmless 30 years ago is not a wise choice today. Many of us did it "back then" because we didn't know any better, but if you are still doing so...you have not learned much over the years.
And judging from your spelling and grammar, I think you may be experiencing other effects that you are unaware of.

The EPA will love this even more than Vinegar and Hydrogen Peroxide!
The shooting it out with a light load is what I would do, I might even try a primer only first after opening up the flash hole before priming -- used to make wax bullet loads for quick draw practice doing this, surprising how much power just a primer has.
Its all in the fine print of the chemistry gold and mercury make a stable non-toxic material. Lead by itself is not too bad, but reacting with stomach acids makes it very toxic if ingested. Vinegar and Hydrogen Peroxide make lead acetate, one of the most bio-toxic of the lead compounds.

Alloyed with silver so the mercury was no longer free.
dental fillings are mixture of mercury (50%), silver (~22-32% ), tin (~14%), copper (~8%), and other trace metals.
Guess I better get rid of my stick barometer.
It has multiple ounces in mercury.

Heck, the cracks between the boards in the oak flooring in my old high schools science classroom was silver from wall to wall!!
Today, that school would be declaired an EPA Super-Fund clean-up site I betcha!!
It didn't hurt me anyyyyyy --- ahhh crap -- excuse me ---- I drooled on my keyboard again.

WWII Mark 2 pineapple grenades were loaded with either EC Blank Fire powder, or TNT. The fuzes were not interchangeable. The TNT required a detonator type fuze (M5 or M6), while the EC powder used a igniting fuze (M10) similar to the one in smoke grenades, but with a longer time delay (4-5 secs. instead of 1-2 secs., I believe).

What's with all this fussing about the lead end? I still don't understand why you can't just twist and pull the wood back out. Use a rod puller if you don't have enough purchase.
Also, if the lead slug is lodged with a space between it and whatever charge you plan on using to shoot it out, won't it create a dangerous spike akin to the pressure buildup from a short-loaded muzzleloader? I did that once with a smooth rifle and the recoil was enough to knock the wind out of me.

Huh? A common way to deal with a muzzle loader where a ball has been loaded without powder is to introduce powder through the cleanout screw or into the bolster after removing the nipple. That usually works and neither blows up the gun nor causes any excess recoil.
A short load (powder charge but ball not rammed down on the powder) can just be shot. The old story that the gun will blow up from some mysterious effect of the air gap is just that, a story. Yes, I have tried it a number of times, several times just to prove to people who believed the gun would blow up that it wouldn't.
