Joking aside, you need to be very careful using soft metal plate targets. Clipping the edge can send bullets off in odd directions with considerable velocity.. The danger area behind an ETR is witness to this. They can also strip and sling jackets back at you from considerable distances..Found a 2m by 2m redundant diversion sign blown into a field laminated aluminium and plastic chopped it up for targets shows de oles well
In particular solid brass and bronze bullets have a potential to create very long range ricochets because of their lack of plasticity..
