    Iron sights and calculation bullet trajectory...

    I'm not quite sure where to ask it so I figure this is as good a place as any.

    I'm attempting to use ballistic calculations to get a zero for a couple milsurp rifles I have using a 25yd range. I know with scopes you adjust your calculations off the scope center height and I'm assuming that something similar can be done with iron sights but as I try to work it out in my head it just leaves me lost. I'm thinking I would measure half the barrel diameter subtracted from the the top of the sight blade?



    Does anyone know how I would measure my iron sights to figure out trajectory?

    Thanks.

    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle.

    If you're dealing with your No.4 or any other Lee Enfield for that matter, you really ought to pick up a copy of the 1948 Rifle and Bayonet Infantry Training Pamphlet No.3. It's all there. 123 pages worth of priceless information. I have them available if in need. Get them while you can because I won't be printing any more.

    No, this is actually for a Mauser and a Swissicon G1911. But I’ll probably hit you up about the pamphlet.

    You're basically correct. I always use the height over bore dimension measured from the top of the front sight blade to the centre of the bore.
