heating barrel 1891 argentine

a cobalt drill bit wouldnt touch it

That sounds very hazardous for your barrel!

If you really want to drill into something that is stuck in the barrel - for instance, so that you can use an "easy-out" screw extractor on a long rod to pull out whatever it is - then you MUST use a sleeve over the drill so that it cannot touch the bore. One touch and the barrel will be FUBAR.

And think again about what Chuck wrote: get it all as cold as possible, and then use a brass rod to drive it out or, if you use a sleeved drill to drill through the plug, a screw/tap extractor on a long rod.

Another thought:

Apart from the throat, a barrel is basically parallel. I have heard of terrible jams using those undesirable objects known as bore snakes, and one could imagine that if a cleaning rod has snapped off, then the break in the rod will be crystalline and very, very hard on the surface. But it got in there - at least until it jammed. So if you want to get it out, you must not keep on pushing it in the same direction, as that makes the jam worse.

Get a bore light - or make one from a small LED on a length of fine twin cable - very simple. Then look down the bore from both ends. Find which looks like the broken end of the rod ot whatever it was.

And then use the cooling trick and drive it out from THE OTHER END so that you are (I hope!) releasing the jam, rather than tightening it.

Good luck!

Well the neither the cooling or the heating trick worked.The item in the barrel is flush at the start of the barrell and is about 4 inches shy of coming out of the end of the barrel.I heated to 350 degrees no help. Tried freezing the night before no help. I have a buddy with a propane blacksmith forge gonna try that next weekend maybe I can get it hot enough. Thanks again for the input Patrick.
