I always check Grafs.....
and others for 5000....
especially for Magtech primers
$137 to your house at the moment
http://www.grafs.com/retail/catalog/...roductId/23592
and if you can afford 10K...15K.....
$21/1000 plus hazmat
Unless I get super technical on a super round.....
any small pistol primer has always been fine.
