Has anyone tried the 22 Bator in 223, 223Ai, and 22-250? A friend of mine sent me this mold and was wondering if anyone has played with them and had any success with these or other rounds?

Thank you for any help I can get.

I've been shooting them a bit in the .223. I've been filling the case about half way up the neck with WC 852. Group at a hundred goes about 1.5" when I do things right.
