I reload after every engagement. Not kill, necessarily, but every time the shooting stops or i get a break, i change mags. Whether it's in a video game or paintball, it makes no difference.
As a side note, if you're like a lot of people who reload and then get shot because of it, you should try paintball or airsoft. You will never reload at an inopportune time or without covering fire again.
