When I shoot in day I hide. When i lamp I stalk. I use gen1 now so don't lamp often but i offer some tips.
Learn airgun ranges and preception of range at night.
Don't over use lamp as rabbits will be spooked
Red filter works well if they are spooked by normal light
Get in closer when lamping than shooting in daylight
Keep an eye on your shadow, don't walk with the moon behind you
Keep the wind in your face
If somebody else is holding lamp then keep barrel level with lamp.
If the bunny runs shake the lamp as this often confuses them
The bunny will often run to the side of the field but will take a few moments to get its baring
Keep scope mag low (around x4).
When stalking keep lamp off and only use for a few seconds to spot eyes.
Good luck mate.
