Check the internals and make sure you have a good bumper on your bolt guide. You may be getting metal on metal contact somewhere. That's if you mean mechanical kick. If you have a lot of barrel rise then you may need to run a higher dwell as suggested. If you're using a really lite setup(hopper, barrel, tank), barrel rise will also increase.
