Carrying a .224 to hunt TROPHY white tails that routinely rip the scale at 160-200lbs, I would say you are under gunned. The whole shot placement is key this is a load of crap. The fellas that have the luxury to only take broadside perfect shots must have it made. 75% of the areas I hunt youre shooting a max of 100 yards through the mountain brush.
I would not trust any of those bullets to be threaded through dense brush into a hard quartering away 140" white tail.
Okay....Just as an FYI, one of the deer I killed with a 224 bullet weighed 250#, and the bullet struck him at 20-25 degrees angling away and penetrated just under the opposing hide. The damage done to the lungs was comparable to any 243, 6mm or 30-30 I have seen.
Another buck weighed 175# and was shot while hard quartering away by a 22-250 at 350 yards and using one of the above bullets, and he went DRT. The bullet exited.
No one is debating other calibers may be more suited for certain situations, but that proper loaded 224's are viable, proven rounds for some situations.
