Loading data for a HBBS 44-410 overbore slug gun

I am searching for load information for a friend of mine for a Hoenig Big Bore South .44-410 Overbore. I believe he is using the full length brass cases. I am clueless to these things and have almost no interest in it, but he is my closest friend and he is doing the loading as a favor to some other chap.


P.S. I am glad to live in a state where you can hunt with anything over .23 for game animals!!!!!!!
