The rifle should balance at the front action screw when it's ready to hunt. Making offhand hits with a rifle that's light in the muzzle is far harder than with a rifle that's neutral or muzzle heavy. Muzzle heavy without a scope is a good thing because adding a scope shifts the balance point to the rear. If forced to choose between muzzle-heavy and muzzle-light, I'll take muzzle-heavy every time.
