The 7mag is just way to much power for deer and if you don't hit massive bone it really just punches a clean hole through them letting them run a good way before expiring.
This statement is disconnected from reality to the point of absurdity. In fact, it not only doesn't apply to the 7mm Rem Mag, but it doesn't apply to this physical world.
Maybe in the Twilight Zone or some alternate universe, but not here.
The harder a bullet strikes a target, the harder the target strikes the bullet. Equal and opposite is one of Newton's Three Laws, and everyone with a middle school level science education knows that as it applies to us, the faster we push a bullet the greater the chances of bullet deformation--whether it be from expansion, fragmentation, or whatever. Regardless of caliber, bullet weight, style, or construction, you will always have a greater chance of getting expansion or deformation pushing it at higher velocities. There are no exceptions to this, none. And it is physical fact. It is impossible to push a bullet too fast to have time to expand or any of that nonsense.
If you're not experiencing expansion with a 7mm Rem Mag in deer without hitting bone, you are using a bullet designed for game heavier than deer. Change to a lighter constructed bullet. But the fact remains that the velocity achieved by the round is not the culprit, and in fact, slowing the bullet down will show even less expansion.
Furthermore, I already showed that the 7mm Rem Mag produces only marginally more recoil than the .30-06, so I don't know what ya'll are complaining about.
