First of all, I have come to the point where I simply don't expect the same level of excellence from any factory ammo as I do from my handloads.
Those weaker loads are fine for deer, and having less recoil, perhaps they are easier on the shooter. Managed Recoil, anyone?
Wanting a better selection of higher performance ammo in one of the reasons that many took up reloading. If you don't want to reload, you would be much better served by a 30-'06, even though it too, is also loaded well below its potential.
Maybe some folks like the milder ammo because their kids can get their first deer with Grandpa's old rifle and they like the brass to reload with something a little stronger for moose, perhaps.
If you want premium ammo, you can find it online, but don't expect it to be cheap. For that, you simply must reload.
