So, let's get some numbers out of the way.
Headshot Damage: 80
Bodyshot Damage: 32
Total DPS: 128
Average DPS: 96
Refer to this sheet for ttk and dps vs other guns
The Grandeur's bodyshot dps is now 128, 96 on average. And in terms of TTK and damage output, it is outclassed by the majority of the automatic weapons. Even if you land a single headshot, it is not enough to finish off people sometimes because of limb damage. So you'll typically kill in 3-4 shots, and that's while you wrestle with aim punch and the recoil.
If this is how you're going to leave it you better change the accuracy, cause right now the gun is almost borderline impossible to get consistent results with. You have to nail double headshots to win your fights, period.
