I was going to add same. I have a quantity of Winchester stayless that are domed. Probably 1950's. They work just fine for me. But its determinant in how where they have been stored. I have a brick or three of those green CCI's myself! Hahahano problems.
I still have a few rounds loaded with domed primers that come in little wooden trays, and a few more boxes of them in the cabinet [the barely legible tag on them says 19 or 29 cents]
every one of them has done what they are supposed to do.
