It may be familiar to some but I just came across a reference to reinforcing the base of CBC (Magtech) cases by pouring molten lead into the base. I know that the original Boxers used papier mache in their base but lead is a new one to me.

Can anyone usefully comment?

Sounds like it might result in an over-bore-size obstruction in barrel if it was to loosen on firing. Also, in the past I've annealed brass case necks by dipping them into molten lead--wouldn't the same thing happen if you poured molten lead into a cartridge case? The lead would cool quickly, but would it still be hot enough to anneal the case head?

Some one who did this absolutely has no idea what the are doing.  Pour  molten lead risks the real danger of annealing the  case head weakening it.  Don't do it.  You may not get a full anneal it may only be partial.  You do not want soft case heads, that can fail.

There was available in the niche market fiber head wads.  Years ago when we first started using these CBC cases some folks used head wads to make reduced capacity cases. The are inserted in the case and held in place with water glass.

I googled and could not find a head wad supplier.  I didn't look hard but I am sure they are out there.  Before you go messing with them read up on shot shell load and the war ig as about changing powder volumes. There i s a reason shotgun shells  have specific recipes for specific shot shell cases.
