DMR challenge Headshots

Honestly this challenge needs to be changed entirely. The DMR's are absolutely terrible. The only way to get a 1 shot headshot is to headshot someone with the SVK-8.6 within 10m, but who in their right mind is using a DMR as a close range weapon. Anything outside of 10m will not deal enough damage to 1 shot headshot, unless you have hollow point rounds, but in order to unlock hollow points you need to get the gun to lvl 30. For reference I've been sniping exclusively with the ESR since I started playing, I have around 45 hrs in the game with a good chunk of my play time being recon and I still don't even have the ESR at lvl 30 yet. That means that the only way to get a 1 shot headshot for me at this point in time is to either shoot someone who's already partially damaged, or 2 tap people. I'm not saying this challenge is impossible, it just takes a bit of time and patience to lock in with the gun but good lord is it unenjoyable to complete. IMO with the state of current DMR's just getting a headshot kill or not should count towards the challenge, or the total number of headshot kills should be reduced (furthermore the wording of the challenge should be changed to reflect the correct requirements for the challenge)
