If my gun requires 4 clicks per inch at 100 yds, how many clicks do i make at 25 yds?

Also, if I want the CVA Powerbelt bullet (50 cal, 295 gr with 100 gr pyrodex pellet) 1 inch high at 100 yds, where should I try to get it to hit at 25 yds?

I just mounted scope and want to sight in tomorrow am.

thank you
