    might be cheaper because they're plated, not jacketed--the lead core isn't dropped into a copper disk that gets pushed around the core; the core is put in a chemical solution that deposits jacket material all over.

    Better, eh, maybe a little if you're worried about lead fouling from tiny bits of lead melting off the tail of a conventional FMJ bullet and staying in the bore.

    I know an indoor range with such bad ventilation, I'm surprised they don't require it.

    TMJ is also preferred by some reloaders as a way to reduce lead exposure as well.

    My indoor range requires some sort of plated rounds. Has to be moly-coated, FMJ, or TMJ.
