One thing to be aware of with that 185 Remington 8mm bullet is that it was made for 8mm Rem. Mag velocities and it will not open up very much at 8mm Mauser velocities. It is fine for punching paper but for use on game I would go with the 180 Nosler ballistic tips or 175 Sierra or for deer size game the 150's from Sierra or Hornady or Speer are the ticket. IMR 4064 and Varget are too very good powders with this caliber. I second the statement about the Sierra accuracy loads.
