For steeply declined targets the hand may have to be inside the leg (not sure if outside would work?) in the air and the rifle supported off the hand. Course setters should ensure that such steep targets do not make it impossible to address the target when kneeling without forcing the competitor to adopt either an illegal position or an unsafe address (e.g. not shooting their forward foot).
It would be like taking a prone shot and placing the hand on the ground and resting the rifle on top of the hand as in HFT.
One could argue that the knee bones connected to the shine bone,then the ankle and heel bone, so in theory you are resting the gun on the ground like in hft.
It does not say you cannot support the hand with the knee.
