One other thing to bear in mind is that the pins will be fairly close to each other, as that is the nature of multi pin sights. When setting up you may find they are only adjustable for a narrow range of distances. If you compare highest and lowest settings on a target sight for
compound with the range available on a multi pin, you will notice the difference.
My 60y setting is 32mm below my 20y setting. With a top pin set for 20m/y I would guess my longest range available with multi pin would be 50m.
Looking at some multi pin sights they have a scale on the side that can give you up and down movement of the sight ring. But that would possibly give you sight marks for 70m down to 40m and anything closer would mean adjusting the whole ring on the scale which changes all the pins at the same time.
