I may be late and you may already be aware, but you have to charge the wand to fire it. I've never personally had it fail to shoot that I can remember, just me releasing just a bit too early.
had the same issue. Turns out it has to do something with the framerate. I used Rivatuner Statistics Server to limit it down to 60fps and that fixed all issues I had.
I found a very good solution. Just reduce your monitor's refresh rates from Windows settings and you'll be good to go! It solved every problem I had with the game, and suddenly I was faster.
