[Brian McIlmoyle]

All BBs are harder than skin..

All bbs will break teeth

The energy carried by the projectile is constant over Mass x Velocity regardless of the material. Particularly considering dimensions are also constant.

Getting shot with a glass BB is no different than getting shot with a plastic one of the same size and weight shot at the same speed.

From a physics standpoint all the "issues" with these bbs are unfounded.

my only issue with them are they are a bitch to clean up

upside is for a home plinker shooting into a proper trap.. they are very likely re-usable
