.416 Rigby, anyone?

Would a run of 400 RNFPs interest anyone?

PB?  GC?  I’m not normally a fan of combo molds, but this might be a reasonable place for it; some days the inner masochist wants the full elephant rifle experience, and others, not so much.  I’d be after 4 or 5 cavities.

Something you might consider Al:  on African rounds like the Rigby and the big .458 magnums, cartridges can be loaded on both sides of the gas check threshold as well as both sides of the shooter comfort threshold.  Making a 4 cavity mold with one of the cavities gas-checked or a five cavity with one or two gas checked would give most folks a nice ratio of maximum practice to heavy hitting when needed.
