Well, in all truthfulness (and I'm not pointing fingers, I'm merely speaking about how I go about things), I would consider this clearly screwing around.
I'm all for fun, safe, controlled "screwing around" but this isn't the sort of thing I would do on a publicly accessed shooting range.
This is something we do on private property.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
