Don't confuse Plated RN with FMJ-RN. One is not the same as the other.
Everglades' cost more than Zero Bullets. Do they actually make them or buy them? Just curious--they will certainly go into my list of bullet sources (but they would have to be unbelievable to be better than Zero).
There are some insane indoor ranges that believe that exposed lead will put lead in the air, ignoring that the time from ignition to bullet exit doesn't give heat a chance to even burn paper, much less melt lead, nor does it take into account all the lead from the priming compound. However, I never heard of one of them actually disassembling a round to check the bullet.
