Could you take a look at my MG 17 mod and tell me what I am doing wrong?

I am trying to increase the lethality and firepower of the MG 17 without changing it's trajectory characteristics. I want it to be stronger than a M2 .50! I based my mod off of the M2 .50 mod found here: 

I tried changing many many values and increased everything by 10x, but the MG 17 damage is still too weak. It's as if my edits are doing absolutely nothing. Can someone take a look at my mod and guide me in what I should change or tell me what I am doing wrong? Thank you.

Here is my current MG 17 mod: https://www.mediafire.com/file/et3au82x9owejon/MG17_Damage_Mod.rar/file
