Basically I channel my spent primers into a a jar,whose lid I secured under my bench,(I twist the jar on an off as it fills up.) Once the jar is full I seal jar with a similar lid,and place the jar into the brass recycle bucket.
I try to use a fluid funnel,and a piece of PVC flex tubing to gavity drop the spent primer through my bench into the catch jar.
There are several similar videos on UTube
'Steel cuts flesh / steel cuts bone / steel does not cut steel.'
Become steel or get cut.
