If you don't want to reload this brass [easily decapped with water and a broken-tip Lee 30 caliber decap punch (no pin)], I'll offer 11 cents a piece (up to 300 pieces) if you will ship it to me. A USPS small flat-rate box should be able to handle 150 or more cases, I'm guessing.
Scrap value is 4.9 cents (case weighs about 194 grains; 36/lb., basis: $1.75/lb).
For that matter, if you ever get down around Foxwoods, you're welcome to bring your rifle and brass and I'll work with you on reloads for your K-31.
I reload/shoot mostly reduced cast loads, using the Lyman 311410, which makes for economical plinking on my 100 meter range.

About the only other projectile I have in .30 caliber at present is a sabot load which uses a .224" bullet. I'll have to do some casting, since a RCBS 180 grainer (

If you have bullets of choice, bring them, too (I don't have many rifle powders at present beyond W748).
KBCraig: My RCBS tool works fine, but I prefer water to avoid any marking along the extractor groove. Try finely adjusting your cutter. Too deep, it may snap the cutter and/or damage the anvil. Too shallow and it will tear away at the primer cup until there's nothing left to catch.
FWIW, the SF308-125 NTP (

Oh... and don't neglect the plastic bullets either:
You could probably shoot these in your basement with a suitable backstop.
