Yowsers!!!

Guessing at the powder charge I get 182 ft pnds kick with 50 fps velocity for the 460 Wby.

The 600 calculates out to 240 ft pnds with a velocity of 51 fps.

My hats off to you-- no way am I gonna get near anything like that.That falls in the catagory of signifigant pain and agony and can break body parts--
