They are getting more and more common in europe, especially with the nontox ammo from S&B but also other brands like RUAG/Geco. The leadfree primers are weaker then normal ones, might optimise the flame... RUAG/DAG now even goes back to berdan flash holes but with boxer primers. I assume its to keep the pressures low in the primer with the +P+ action 4 duty ammo. Gesendet von meinem Redmi Note 4 mit Tapatalk
