There's a fella (BishopofBling) on CTGuntalk with some o-f 8mm. He sold his Mauser, doesn't reload. He has a bunch of ammo, too, but he may not want to bother shipping ammo.
"I brought this ammo new and shot it but I don't reload and I sold all my Mausers so I have no need for it.
142 rounds for $20 that's 15 cents a round.

Good luck.
If picking up brass in North Stonington, CT is handy for you, I will see BishopofBling this Saturday and can pickup this brass, if you make a deal with him.
Still, probably more sensible just to pay for a small flat-rate and save the drive.
