Frosty Boolit

Have two Alloys:
-Frictionless babbitt
-Mystery metal
In a .357 158 grain swc mold that casts a 157-158 grain boolit the frictionless makes a 143 grainer and the Mystery metal casts a 103 grainer.
I'm thinking the frictionless is a lead based babbitt, but I could not find much about the composition with google.
Mystery metal was in ingot form from an auction. Thinkng maybe it is tin.
Mystery metal is tin, figured it with ratios and relative densities but the other one is a bit more complex.
