Yup, you're right. I had a brain fart on the WW cases. I knew RP was the only maker (other than soon to be Nosler). I tend to use WW cases for everything else. Let me correct myself by stating I'll be using WW cases. I went ahead and ordered a Redding tapered button just in case I get a wild hair to neck up WW .243 cases. Just not crazy about the donut issue everyone has spoken of.
