Sorry, Eric...I misunderstood your opening question.
I thought you might be asking about re-loading and ballistics and such...did not know you were just looking for another supply of ammo.
Glad other folks helped you out with a supplier.
BTW...Sportsmanguide.com still has 7,65 mm (.30 luger) as part number # WX2-7343. Not as cheap as the Finnish Lapua stuff they sold out on...
