WTT - 4,500 Winchester Match Ready Small Rifle Primers

I am looking to trade 4,500 Winchester Match Ready Small Rifle Primers for CCI 450, CCI 41, or Rem 7 1/2 primers. These primers give me single digit SD and ES numbers in Lapua 308 Palma brass but my large firing pin tends to crater these so its easier to just switch to a different primer. At current market prices estimated trade value is $450 to $550. Please PM with offers or questions. I am in the SE Valley Gilbert/Queencreek area.
