Well, it would be all about jamming the shell using its own momentum. It's not about creating a plug.
For instance, a wedge, if not blown out, would force the shell against the side of the barrel and is either going to explode or severely damage the barrel.
@jurban @Render Maybe. It depends on if your blockage has enough friction against the barrel to significantly deflect the round. A tank round sits around a few million joules of kinetic energy. Redirecting that enough to damage the barrel would probably require you to weld it into place. Otherwise, barrel scoring and getting blown out the front.

Then maybe try to get the shell to explode? Hit the nose? I suspect they have a delayed enabler so they don't explode while being shot.

Who said it was a shooter? 🙂 That's the secret sauce.
@jurban The rounds are already wedged in rifled and in smooth bore guns.
Packing Ukrainian Black mud into the barrel to a depth of about two feet works.
But if one can get close enough to a Russian tank in Ukraine to do that than a hand grenade down the barrel would work quicker.
@jurban @Render Nails, by themselves, probably wouldn't do much. Just get blown out the barrel.
Not sure what effect an epoxy plug would have. It would be pretty hard to get a significant plug in there with a good bond. If large enough, will create a significant overpressure and break something, but I don't think anyone is going to let you sit around with hot glue and buckets of epoxy.
