Sim Rounds are real bullets fired from real guns, just the bolt is switched so it fires them at lower velocities. You can sometimes see them, hear them whiz by. I’ve dodged them before, it’s not a impressive feat. I’m sure if you had a baseball bat you may even Jedi Wack them.
But no, a normal velocity bullet, once fired, if your reacting to the sound, can’t be dodged. You can however, dodge the guesstimated trajectory of further shots.
