20 year old black powder loaded 45/70 any good?

[Martin Luber]

Loaded these and never used them. Someone said theyve corroded inside and the body will break off and stick in the barrel?

Thoughts?

Doubtful they have gone bad unless exposed to the elements. BP in a closed space in normal conditions will last a long time.

Someone took some apart????
Better send them to Me for Proper Disposal!!!!
Some attempt at Humor there...But, serious about Not tossing until it is Known...

nonsense I have shot lots of old German military from the 1880's. I've had cases fail by cracking but nothing was blown down the barrel. And so what if it did? Fire one. check your bore - have wiping rod handy just in case.
