Supposedly Stopping Power has no effect on the WA2000, unless youre using SP for the Rafficas, I recommend cold blooded.
Not entirely true.
Stopping power just doesn't have much of an effect on the damage due to some bad multiplication. Simply put, stopping power will only make it easier for you to kill already injured people or people with painkiller on (although it's still not even close to a one-hit kill with painkiller, due to the fact that painkiller divides damage by three).
Keep in mind that all sniper rifles do 70 base damage, 50 silenced, and in softcore, everyone has 100 health (I believe they have 30 in hardcore).
Without stopping power, no silencer:
Headshot - 70 x 1.5 = 105
Neck shot - 70 x 1.5 = 105
Body shot - 70 x 1.5 = 105
Everywhere else - 70 = 70
With stopping power, no silencer:
Headshot - 70 x 1.5 x 1.4 = 147
Neck shot - 70 x 1.5 x 1.4 = 147
Body shot - 70 x 1.5 x 1.4 = 147
Everywhere else - 70 x 1.4 = 98
As you can see, it gives you just under the required damage for a one-shot kill in the limbs. Anything else at that point (such as a grenade impact or a bullet through a thin enough surface) will kill. That makes stopping power only advantageous for killing people in the arms/legs through walls or if they have less than 30 but more than 2 HP remaining (which is an admittedly large range). The difference is more pronounced with a silencer.
Without stopping power, silencer:
Headshot - 50 x 1.5 = 75
Neck shot - 50 x 1.5 = 75
Body shot - 50 x 1.5 = 75
Everywhere else - 50 = 50
With stopping power, silencer:
Headshot - 50 x 1.5 x 1.4 = 105
Neck shot - 50 x 1.5 x 1.4 = 105
Body shot - 50 x 1.5 x 1.4 = 105
Everywhere else - 50 x 1.4 = 70
Stopping power makes a silenced WA do the same damage as an unsilenced WA without stopping power. All things considered, using a silenced WA without stopping power likely isn't a good idea unless you plan on being very difficult to spot.
