    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.

    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.
