That's one vote for Sierra.  I am of a similiar opinion.  Casting would be a new skill set and expense and I already have 85 percent of the tools needed for jacketed bullets.

Was sitting here going through the different bullet and powder sites for load data for 30-40 and other cartridges.  I don't recall having any 4350 in the "pile" so that will be on the list once I get back to the States.

Primers?  tens of pounds of WLR.  Powder? As stated. Brass?  Out the whazoo.  Bullets?  See: The whazoo.

Now I just have to get the 1895 from Turnbull's place and start working up loads.
