Hi gents, looking to to run a heavy slug in a regular 12 gauge for the first time, maybe a decent bolt action or one of the rifled turk leverguns. In Australia we have zero shotgun powders left on the shelf, so considering blackpowder.... I have a Big game rifle background but no experience loading shotgun or blackpowder. I do know you can get healthy power from loads of black behind big slugs though which is what I am after
CBE moulds here for 770-820 grain slugs

or heavier..
brass cases/ black powder, whatever it takes. Not worried about recoil, can be as stout as can be.
Thanks for any ideas or general advice to get started.
