Sorry I can't help with that specific info, but just bear in mind an indoor range is unlikely to be long enough to really do that for you...
I'm lucky enough to have 15+ metres of garden to use for test firing, and that's enough to zero the sights for windage, but it's only just far enough to show the hop is having any effect - you'll need 40+ metres to actually get it corrected for the game.
Best of luck though!
