I have hunted WT deer with a 44 mag RedHawlk for 10+ years .
I have shot deer from 3 feet to 100 yds ( most are 30-50 yds) and never had one go more than 40 yds .
I don't feel I need to lug 20 oz more gun ( 73 vers 53 ) to the blind to do the same job ,only to have it mess up more meat.
True you will be able to shoot a deer farther out .
But MOST hunters don't practice enough due to being cheap , lazy , not having access to a range to use the extra range the 460 cart. has.
Some "hunters" will buy the gun to have the new toy or think the extra energy will be the silver bullet to make up for their lack of skill or practice.

Yes in the hands of a few it will be usefull but for most a 629 or Redhawlk is a better choice IMO.
Few years back I thought I needed a 454 Ruger Super RH , I down load it to hot 44 mag loads if I use it ( 250 gr XTP at 1450fps)
