Those Norma bullets look just the ticket, Ed. We are in the same boat. I have a Dickson Steyr .375 coming. I hoovered up an old box of Hornady 270 round noses at Tulsa, and found some 300's a month or so ago. The rifle has proofs for 320's, so I wanted the different weights to try. Also got some .405 Winchester cases to squash down too, now all I need is dies and I'll ready to go.
