Nerfing sniper rifles

[Shurp]

So I am tired of pirate sniper rifles blowing off my colonists' arms and legs and I need some advice on how best to adjust the damage they do to reduce this.  Sniper damage is 40.  What defines how much damage a leg or arm can take before it is destroyed?

[edit] ok, I found this, which makes me unhappy:

Leg is listed at 30 and Arm is listed at 20.  Which means I would have to knock off over half the damage to keep limbs attached   Or I have to make Devilstrand dusters and pants commonplace.  Or maybe some combination of the two... if I reduce the damage to 30 then any armor value will keep a leg attached and 33% armor will keep an arm attached, correct?

i made simple modification about balance and difficulty, basically removed "rageout" feature obviously hook based c#...

no hit may reduce hp of bodypart below 1.
saving throw apply debuff on bodypart, bodyparts with debuff have no protection

No, that's way too complicated for my level of modding skill.  I'm looking to balance the game with something more basic.  I've already added varieties of devilstrand to provide some weak protection.  I just want to fine tune the numbers so that the first hit of a sniper rifle won't blow a leg off but the second will.
