This may sound silly, but im going to post it anyway.
I learned to reload when my father and I were shooting competitive trap. We would often shoot 600rds per week. I was in charge of loading the hulls.
You may already know that half of trapshooting is 90% concentration. I learned to take the same concentration level required on the trapfield, and apply it to the loading bench.
I'm serious when I say that reloading was good practice for trapshooting, because I was working on concentration level.
Do any kids reload now? My grandkids concentrate on their phones.
