Reload sound doesnt match reload state of gun

Hey guys,I have found out something that happened to me several times. Until now I didnt recognized the issue.If you reload a weapon the sound of inserting your mag into your weapon signalizes yourself that the weapon is reloaded. (At least that is what I am asuming)

Now to the problem I have. After several hours of Halo you just know when the sound of the mag appears and you get the hang of when you can go back to sprinting while reloading. Problem is: The sound appears slightly before the gun is acutaly loaded. This leads to several deaths with an empty mag which should be full.
Here is a clip to visualize the problem.Dont know really know if this is a bug or I am just having this issue. But it feels slighty weird.

Hope someone can shed some light on this! :)

I’ve never had this issue, the sound and reload are synced quite well for me. Also it’s about a fifth of a second after the sound…
