I had a bunch of misfires with Win small pistol primers that were bought around '10-'11. I bought about 2k of them, they gave me fits. All from the same lot. Misfires in different guns and chamberings, so I knew it wasnt a gun problem. Called Olin, the basically told me too bad.

I havent bought a WSP since then, nothing but CCI's and no issues.

There is no way to coexist no matter how many bumper stickers there are on Subaru bumpers!
