I was in almost an identical position to you, I sold my 2nd 9.3 DR, and was left with a heap of cases, projectiles, and factory ammo. I decided that I would sell it, and did. Nek Minit I buy a Ruger No1 in 9.3x74. Need to buy new brass and projectiles, at great expense.
Don't sell it, you will be sorry.
