Has anyone rebored a CZ 550 375 H&H to a 416 class caliber; e.g., 416 Remington, 404 Jeffrey, etc.? Is there enough muzzle diameter to do so safely. I ask because I have a line on an inexpensive CZ in 375 H&H and no need for that caliber (I've got a 9.3x62).

I hear Jim Dubell took over La Bounty's operation, 509 684 5855...he'd know

You have a PM.

yes, without a doubt.. and brockman and ahr have 416 takeoff barrels ... cheap and easy

I had this done some years ago on a ZKK 602 Brno in 375H&H,I'm lead to believe the barrel contours are the same, the results were entirely satisfactory.
