With life being a stream of compromises and non-guarantee's how much wt. should one put on the potential for over penetration with the hardcast in the urban environment? Worth carrying standard defense rounds (fed hst etc. etc.) in the spare mag to swap over to when situation permits, or..? I'm not familiar with stats. on noncombatants(nc) being hit after projectile penetration of the original target so reason for my ?'s, maybe not a practical concern? There are shooting techniques to prevent hitting nc's via pass through's by dropping down to one knee/lower firing position etc. to shoot up through the target sending the bullet/s above bystanders but you may not have time, so...? ..Am I over thinking this?
