Cut metallic heavy stone id help please with cross sections pics

[Callahan]

Any mineral experts have any idea what these stones I just recently cut with my wet saw?

 

1-7 pics

 

heavy extremely magnetic river find.  Cut in half.  Possible 1800s bullet making ingot  raw material to be melted or long shot a meteorite?

pics 6 and 7 are outside and heavily weathered.  Almost a wafer looking rock. 
 

grey streak from cut side.  Brown streak from weathered side 
 

8-11 pics

very heavy non magnetic at least with my fridge magnet I’m using. 
 

cut in half super shiny when polished.   Cut side is not completely polished either. Still has cut marks on parts.  
 

seems to have so called melting marks etc. 

 

grey streak from polished side and brown streak on weathered side on ceramic

 

Will send gravity and better close ups of rocks if anyone that’s interested.  
 

I need to do gravity on some other unusual minerals I’ve found also.
