Sight adjustment, check my math

[Beerd]

I went to sight in my 444 Marlin yesterday afternoon.
At 100 yards it’s hitting about 14” high.
The distance between the rear peep and front Firesight is 25”.
How much taller does the front sight have to be to bring the point of impact down 12”?
(I ciphered it out already, just looking for confirmation.)
Thanks.

Error"x sight radious" / distance " gave me .833333333 also.

.8333 is not .083

Yup round about 7/8 would be kinda tall on the end of that barrel:kidding:

update:

I changed out the .250" front sight for one measuring .340"
Tweeked the rear sight up a little and it's now shooting where I want it to.
