This is easy. Go shoot and zero it at 100 yds. Then shoot it at 200 yds and see where it hits. Adjust towards the point of aim. Shoot and see where it hits. Once you get it hitting your point of aim at 200, write down the adjustments. This should tell you whats going on with the clicks per MOA etc.

I recommend you shoot at each 100 yd increment you can, to verify your drop data.

Good luck with it.
