Lew_Merrick_PE:
Roy -- Back in my youth, BB's were actually made of copper.  I had (circa 1972) bought a 5 lb container of BB's that were used as shaft savers in projects.  A dab of grease made a BB fit really nicely into the cup of a 1/4 inch cup-point set screw.  I finally ran that container out in the late-1990's and was seriously surprised to discover that modern BB's are only copper-washed steel!

rleete:
Modern air-soft BBs are plastic.  Might not hold quite as well, but certainly no chance of damaging a shaft.

Fredbare:
Just what I was looking for Roy, thanks for sharing.
