Plunk Test

What is the Plunk Test?

[trying2learn]

Dropping a loaded dummie round into the barrel to see if it fits properly. If it does most of the time you will here what sounds like a plunk sound. That's the short version.

Nah, is when ya throw the whole box of shells in da pond jus' after thay blows up yer gun.

[MT Gianni]

Drop an ingot on concrete, if it rings it is lino if it goes polunk it is soft lead.

[MEVS]

throw the accused witch in the lake with sufficient weights. Wait 10 minutes. Retrive witch from the lake. If the accused is dead she wasn't a witch. If the accused isn't dead you're likely screwed.

Drop an ingot on concrete, if it rings it is lino if it goes polunk it is soft lead.

I'd modify that to read if it has any ring at all it is something other than pure lead. Pure lead hits concrete with a real dull thud. Do you 'spose I could calibrate my ears to my hardness tester and thus avoid casting sample boolits from each melt for my Saeco hardness tester? I mean,... geez, you can tell the age of a tree by it's rings!
