If you use no-powder rounds always confirm there's a hole in the case and the primer is blown when you load them in. Additionally, the top round should be something highly visible yet good for reloads (like the mentioned orange snap caps) and the one in the pipe should be stupid visible (those retail store red ones are far better for this as their case section isn't silver).
Dummy rounds should either be made on a press or purchased retail for their actual weight, otherwise they're completely useless. The whole idea is you have lead weighing your gear down properly. Other than that backstop = good, no live ammo = good, and no practice when you're tired = good since you won't get much out of it. Live and learn.
Also, while it was an A it looks like you flinched a little low left.
