Why doesn't the bullet register sometimes?

Hello to whoever reads this!

I have about 100 hrs on BF6 both redsec and regular, playing on KBM, my PC is high end with a good consistent 5 ping on the Australian servers, but I feel like as if my bullets do not register a lot of the times... 

My anecdotal experience is that I believe there is a some type of delay for the KBM players when trying to "hit" the CONTROLLER players no matter the distance there's like a delay or its as if there is a miscommunication between my PC and their console(I know this makes no sense but I am clearly not a dev or a coder I'm just trying to be as transparent as possible) so what I am shooting at is actually not how it is server-side. I feel as though when I am fighting against another KBM player I can feel their shots and they do mine equally and fairly.

A reference to this is a video of a streamer; Shroud when he was shooting at an enemy basically point blank and its just not registering at all. I feel as though this happens a lot more in redsec but thats all i have been playing since its release.

Having 15 years of FPS games, the real players that will stick around at the end of the day only worry about the core mechanics of the game. Whats the point of investing another 100 hrs or any MONEY into the game if half my bullets end up in the shadow-realm?

Much respect and thanks to the dev team! you guys are doing great atm, with frequent patches that actually fixes this game that people are talking about. PLEASE do not turn into corporate slaves like your competition CS and COD & VAL, only patching to add skins to make more money and never fixing their core movement or bullet reg or any of the bugs that's been around for 15 years.

Thanks for taking the time to read this
