P,
They cover similar ground for similar purposes.
At usual hunting ranges, not a lot in it. (That is obvious)
At longer ranges, perhaps the trajectory of the 7 may be an advantage for some who know how to use it.
For over sized or potentially aggressive game, the larger heavier bullets in .30 cal may offer more "comfort".

For the rest of us, the rifle is more important because we need to like to hold it, carry it and shoot it.
