Home Forums Hunting & Shooting Hunting Rifles Its possible that a .223 works on deer better than 30-06?

my point is that I wonder if a 3000+ fps .223 round that goes all the way thru is more damaging to the deer than a 2600 FPS 180 grain 30-06 bullet that goes all the way thru or a 2400 fps 358 bullet. What role does velocity play as long as you get full penetration? Secondly does the .223 because it is smaller impart more work to the innards of a deer as it probably loses more velocity while its going thru.
