no, it is not to much gun for a deer. i am not really sure you could have to much gun for deer, unless you start digging out cannons. a Howitzer WOULD DEFINITELY be to much gun! my definition of to much gun is one that does way to much damage to an animal, so as to ruin much of the meat. a 458 Lott would not be to much gun for a deer. it would be to much gun for ME, but not the deer. dead, is dead. when people say it is to much gun, to me that means it is to much gun for them. i can understand that. not everyone is cut out for big recoil. i shoot deer with either a 300 Win. Mag., or a 45/70. both have a pretty stout recoil, so to some, they would be to much gun. but, i only had one deer go anywhere after being shot. and it was hit after the bullet went thru an oak tree. even after that, it only went about 70 yards. i can handle the recoil fine, and shoot both of them year round.
