Brutal I am not into. My .72 DR with 780 grain conicals is more than enough. 730 at about 1050 sounds like it is in the same general class. Is there a modern loading that can safely duplicate that? I have been referred to a back issue of the DGJ but they can be scarce and I don't know which one to start with.
Fortunately Paradox moulds are not hard to come by, at least new manufacture.

Just because they say you are paranoid doesn't mean they are not out to get you.
