Urodoji-If necked to 416, sides straightened a little, shoulder blowed out it would hold 240 gr
of powder.Using slowest powder available, in a
30 in barrel, you could get a 400 gr bullet to
3700 fps.I have a case and once was thinking of
building a 458 on it.But figured out that the case wouldn't go 50 reloads, like my 458 HE.Which by the way will get a 400 gr up to 3300 with good brass.Ed.

So I would think that this would be the most powerful sporting cartridge in the world. I cant even imagine the stopping power of such a cartridge. Any estimations?? And would you be going to the hospital after every shot for shoulder replacement. On my recoil calculator, In a 14 lb. gun the felt recoil would be 134.76 ft. lbs.
