would like to ask bro and sis out there, how do you set your say 10 yards, or 15 yards sight pin?

For me, my nearest yardage on my top pin will sit at 25 yards. i cant go lower with that.
there is no more room for me to adjust the pin and the gang adjustment of the housing also to the max.
Any tips or advice to solve the problem. Anybody has this same problem?

If you happens to have a big buck walking by you say at 15 yards. Bro, how would you shoot it.
