    Could you measure one of the bullets ? I'd be interested to see if they are .457 unpatched.

    i might get a slating here but as anyone tried trailboss instead of bp.
    i know of someone from another forum who as been very successful with the gahendra rifle.
    all you do is fill the case with this high density powder to a line where your bullet is seated then weigh it.....then use 70% of the volume as a starting point to a maximum of the original volume

    .457" unpatched ? I'm so confused. I thought it would have to be patched up to .468 ???

    Sorry to cause

    confusion Dave. Try it in your's unpatched, then patch if your not getting accuracy. The bore in my MH is very good, so what might work in one gun might not in yours.
