    Still leading

    Well I've read and read and read. Thought I did everything right and I'm still getting leading. Gun is a super blackhawk hunter. I slugged the cylinder at .432 so I sized at .432 powder coat. Loading in a 44 Russian case 240gn Lee mold. Loading 4.6gns of unique. I'm still getting minor leading in the forcing come. This sucks I've got a lot of money wrapped up in this to not be able to shoot them

    Does your barrel have a choke point at the forcing cone or where the barrel screws into the frame?

    yeah gotta think the forcing cone is either really rough or you have a choke point from where the bbl screws in.

    Is the leading just in the forcing cone? Are you sure it's leading? Are the barrel and cylinder correctly aligned.

    Long 44 Magnum chamber - short 44 Russian case + short Lee bullet = space for blow-by before bullet seals in the throat of the cylinder????

    I think it's time to try some castboolit ammo made with 44 Mag cases for that Super Blackhawk Hunter.

    I too would try some correct cases first. I have never cared for short cases in long chambers. That said, I would not be surprised n the least that you don't have thread choke. Its about as common as dirt.

    Are there tooling marks in the forcing cone? If there are you may as well stop with cast boolits in it until you can get that fixed. It will most likely shoot j-word bullets just fine.

    I will try loading some in a mag case and see what happens. I had a lot of these Russian cases and thought I'd give them a try. I will try to get a pic of the forcing cone also.

    There's also minor leading in a few of the cylinders

    Hold on, maybe I misread this. You measured the the slugged barrel at 432 and sized the boolits at 432? Shouldn't they be sized bigger for better sealing? Say size them at .434?

    wheres the leading in these pictures. I don't see any or at least not enough to hurt a thing. A light gray wash in the barrel isn't leading in my opinion. Its when it builds up so that you see rifling filled or accuracy suffers.

    The leading is on the top groove. I couldn't get a pic of it . I put pics of the forcing cone so guys could tell me of it needed anything done to it
