Yes, this can be done but is not really recommended. How much cant is the determing factor and whether or not your ' cant' is very repeatable. I would also guess, based on what you' ve said, that you' re grip is more controlling than what it should be.

If you decide to go this route, you should use a sight that has pins that can be individually moved in the horizontal position. With many of today' s mass movement only on the horizontal level, this may be a problem. You can use a sight without individual horizontal movement, but you would have to compensate slightly. The amount of compensation would be determined by your cant and your bow.

I would highly recommend adjusting your grip, adopting a level for practice and those uneven footing shots, and learn to shoot with the bow level. It might take some getting used to, but it will pay off when shooting on uneven ground.
