223 ballistics chart help?

[Ohio Varmint Shooter]

I can't seem to find the kind of ballistics chart I'm looking for. (if that's even what it's called.)

With a scope that's 1.5" above the center of the bullet (that means no AR rifles), most 223 shooters know if your POA is about 1.5" above @ 100 yards, you should be right on at 200 yards.

But I can't find anything that goes further than that. Under the same circumstances, how high should you aim for 250, 300, 350, 400 yards? I've seen charts that tell you bullet drop at those distances, but that can be different than 'how high do you aim'.

I understand there are things like ballistics coefficient, bullet weight, velocity...etc. Maybe that's why no one takes it past 200 yards. I don't reload, so I'm shooting factory loads, but they're always 50-55 gr V-max. ...and I usually lock onto one cartridge maker for a while. (currently 50 grain Fiocchi.)

I'm looking for a general chart that will help me get close for these extended ranges, so I can start calibrating the vertical dots on the reticle.

Google "Pejsa ballistics" and download the Excel spreadsheet. You will have to input muzzle velocity and ballistic coefficient, because that's how trajectories are calculated. For factory ammo, use the published muzzle velocity. BC is available from the bullet manufacturer.

thanks

With a little bit of information gathering, it calculated what I wanted.
