I have been playing with chaperone in crucible. I've noticed on multiple occasions that if I'm in competitive match and reload as the match ends I will start the next match with that many rounds (one round I started with 5 rounds for my chaperone). Found it accidentally. Grinding for Luna is tough enough. If others discover this it could be bad... Also I would like to note that I am reporting this issue instead of using this knowledge for evil in the crucible, so if bungie could give me a Lunas Howl as a finders fee or at least my glory points that I had when I was first grinding before the reset that would be pretty sweet :)
