I agree with 9ThreeXFifty7, I would not rechamber it.

While not quite as powerful as a 9,3x62 or a 9,3x74R the 9,3x57 is a good hunting cartridge is it's own right.

I have used the 270 Speer in my X74 for deer and pigs with excellent results.

At the velocities of the 9,3x57 I think it would work on moose and black bear as well.

Also take a look at the 285 gr Hawk with the .035jkt.
