I would like to hear the opinion of the distinguished members of this forum concerning the PROS/CONS of the following calibers in a Double Rifle :

450 3 1/4" N.E.

450 NO 2 N.E. (3 1/2")

470 N.E.

The comparision should include the following:

1. Knock down & stopping power for DG.

2. Usefulness as an all purpose rifle/cartridge.

3. AVAILABILITY OF FACTORY AMMO.

4. Recoil.

5. Which caliber would you chose?
