Re: Sharps Rifle sighting in
Your Soule sight should have an ELEVATION knob on the side. Moving your rear sight up will cause the impact of the bullet to rise.
I don't know the brand of your sight so not certain of the MOA on the elevation. (I think 2.5 MOA clicks is standard for windage though.)
To know how far to turn your elevation knob you need to find the trajectory for your ammo, and the MOA of the elevation knob. (The MOA may be in the manual.....or call the manufacturer....the other option is to shoot until you can see the MOA yourself by measuring the distance between groups at same distance when you adjust the sight.)
Here is an example of the difference.
weight velocity 100yds 200yds
45-70 (300 HP at 1800) +2.7" -9.2"
45-70 (405 FP at 1330) +1.3" -22.9"
Once you know the MOA you just need to do the math.
1MOA = 1" @ 100yds. So a click from a 1MOA sight will move the bullet impact 1" at 100 yards. A 2 MOA would move 2" for a click at 100 yards.
MOA doubles every 100yds.
So at 200 yds the click would move you 2".
So if my sight is 1MOA and I want to move my impact up 10" at 100 yards I will turn the knob 10 clicks up. For 10 inches at 200 yards I only need 5 clicks.
Hope this helps.
P.S. 2" at 300yds is nothing to worry about if hunting bison.
