The interesting thing about Fiocchi primers to be made at Little Rock is that they will be lead-free. I predict that within 10 years, maybe sooner, all primers will be. There are several different lead-free technologies available. Federal has been producing some for awhile based on the Thermite reaction, and I believe that is what Fiocchi will use. I have no idea what type primer mix the EXP primers are/will be using. The relatively new AA40 military 5.56mm training round made by Federal uses lead-free primers.
