This will be close to the 445 Super mag.....rimless of coarse. Pretty potent number for its size. Make one really nice woods round. Good cast bullet gun too. 16" - 18" barrel would be plenty to get it to perform properly.

Good idea!

Could go bigger too....use a 444 Marlin reamer with '06 brass and have a rimless 444. No special dies or reamers needed for that one.
