What they should do is something that Tiger Valley did and what I think they did in some earlier Brutalities, is to clear the weapon to be blue, and then do a lot of different movement. That is 100% better, because while you break the immersion by unloading your rifle, at least your movement and weapons handling after that is much more natural. Obviously doesn't make sense if you are just doing a 5 second 30 yard dash, but you get the point.
I think they still do this a lot in Finnish Brutality, where they remove the magazine from the rifle, the competitor then has a "high value shot" for a bonus, after which the gun is clear and they can then proceed to do movement with a cold gun. Doesn't also break the immersion as much when you don't need the RO to check that the gun is clear; it's obviously clear when you shoot your final round from the chamber without a magazine inserted.
