Neat thread. That reloading room looks familiar ... you a member over on the Marlin Owners forum by chance Doc? Seems I have seen pics of that reloading room over there.
You drinking Blue Moon while reloading? Shame on you.
Another cup of sorts, when you can find the right diameter, are straws, (I use the ones from Hardees), crimped and flattened on one end, then waxed-over for the cap although I cap with a piece of paper first to keep the wax out of the lead.
I too use an empty case that I've sanded sharp along the rim to punch wads ... but I use cork shelving liner material you can buy in a roll for cheap. It works great and stays flat when I am ramming it home with a wooden dowel rod.
What you think about, you do ... what you do, you become.
In a nation where anything goes ... eventually, everything will. We're almost there.
