Here is the statement from S&B. I can try to post some picture from their brochure as well if that would help.
"TFMJ refers to the Total Full Metal Jacket bullet design
used in our NONTOX cartridges. This is a closed base
bullet with a lead core. The design limits airborne
lead contamination while delivering accurate, reliable
function in a wide variety of firearms."
"After firing the cartridge is free from
toxic exposure to barium, lead,
mercury, antimony. It does not pollute
the environment, does not endanger
the shooter’s health with combustion
products, and does not pollute
the#gun. It ensures safe shooting in
closed premises and on target ranges.
Unique patented primer design."
