No limestone dosen't knap. There might be some small pieces of flint in there stockpiles but it should be fractured from the shot.

Check it anyway. I used to blast quarries  The charges used are usually slow and break big cracks, we very seldom used 80% nitro, mostly NCN which is a lifting explosion and not a shattering one.

If you find anything promising bub, pictures would be good.
