Free to a good home,unknown maker 30 cal copper gas checks.
These don't fit on the shanks of my cast boolits,tried 3 different size dies they will not grimp on. The shanks on my molds are .285-.286 these may work if your shanks are bigger. There are at least 900 pcs in the bag asking postage only. I think these are made by Vulcan checks but not sure.
