Here's short footage from recent scarh game. There's not much kill in one vid but i think you can see how i play.

Also if i was hacking like 2~4 years ago, why didn't i got banned?
I'm doing absolutely same what i was before. (i started headshooting like 3 years ago)

This is BF3 but you can see how i aim. 5KPM, 30%Accuracy and 30% HSKR with G53 carbine.

This was when i started headshooting with DMR in bf3, i have 80%+ HSKR with them.

Ok, now i'm preparing short footage from recent matches.

the fact how i perform high HSKR is easy, as you said, just aim at your head like in R6S or CSGO

that's for same reason why i'm using SCARH mostly (high accuracy and damage)

as you can see in recent report, i didn't aim at head with AEK cuz it has low accuracy then i realize there's no mean i aim at head. (following reports)

seeing bullet spread, with scar-h, m16 and CZ, there's great meaning aiming at head for getting more kills, so i do.
the numbers are not quite ridiculous compared with Accuracy (17%Acc and 42%Head with scar, Pros have like 25%Acc and 25%Head or so)

so overall, it's the way how i'm playing bf4, experiments and trial.
that's also how i had played when i was in competitive scene in bf4; maybe 3 years ago?

I recently got banned for Aimbot but I do absolutely NOT using any tools
