Gun Building / Re: How to figure sight height
« Last post by bobw on September 28, 2023, 05:34:52 PM »The original question has been answered but sight correction come into question sometimes. The post before this one has a correction in metric. This is an easy sight correction calculator I use in inches.

Appears to be over simplistic as the weight and velocity of the projectile comes into play. This website has no input for either.
LOL, Yes it is, a simple calculator for a simple guy like me!
It’s not a ballistic calculator, it’s a sight adjustment calculator and is only intended to be used with a consistent load, usually after working a load up.
For example, I have a gun in my shop that is shooting a nice tight group, 2 1/2 inches high at 50 yards. It has a rear peep sight that is adjusted as low as it will go. The front sight is a bead that can not be modified. So I either need to make a new front sight or try to find one that will work that is the correct height. In either case this calculator help get me in the ball park, from where it it currently is, where I can get more adjustment out of the rear sight.
Hope this clears up how this is used.
