@C.W. RichterI'd rather not say until it's done and out there! Should slightly exceed the Wby but in a smaller package.
Midway was to bring an old cartridge back to life and add a few mods of my own. I succeeded in my aim and exceeded my velocity expectations with powders like superformance.
If you would like to PM me we can discuss wildcat and I have blackells load from a disc that I might be able to help with load info.
