I am looking at a Belgian .450 express, double gun, boxlock. It seems a little light at just under 8lbs. I can decipher all markings except B. Plomb. I think that means proofed with lead bullets. It had definitive nitro proof markings, but someone on another site suggested that this gun may not be meant to handle standard NITRO .450 loads...seems unlikely to me, but looking for further affirmation.
The gun was Nitro proofed. I would not want to fire a full power load...
My 375 H&H is enough for me.
