    I have a 7mm Mag Sendero Special with a 4.5 - 14 Leupold VX III.

    I am shooting factory loaded Winchester Power Point Plus High Velocity 150 Grain shells.

    According to the Petersons Hunting mag. the muzzle velocity is 3130. I am sighted in at 200 yards.

    According to them I am at +1.4 @ 100, -6.6 @ 300, -19.6 @ 400, -40.4 @ 500

    I want to know my ballistics at 600, 700, 800, and 900 yards.

    Can anybody provide me with this information?

    First,..you must get the true average velocity from your rifle with that ammo. The box can and usually will be off from your rifle. Especially since the test barrel may have been 24" and not the 26" you have?

    Once you get the chrono data,.then go to http://www.eskimo.com/~jbm/ballistics/ballistics.html

    You will need a BC from winchester to input as well as your Velocity and bullet weight and environmental factors as well.
