Spoken for by Swamp.
I have 100 rounds (actually a few extras too) of once fired WW .458 Win Mag brass for sale from my wild and wooly days with a Number 1 Ruger.
I bought 400 rounds off a dealer near the New Haven test range and this is the remainder. FL resized and lightly tumbled.
I'll take $26 and pay shipping. Cash, check, MO or Paypal/friends and family./beagle
