.243 ballistics chart?

[FrenchieBoy]

Can anyone point me to a ballisics chart that covers a .243 firing 70g ballistic tips chronoed at 3,400 feet per second please. I'm interested in the bullet drop at something 300 yards, 400 yards and 500 yards with the scopes set "dead on" at 100 yards.

You'll need the ballistic coefficient of the bullet to get an accurate result. Hornady have one online, and the Zeiss one is pretty good.

Nosler list the BC for their 70grn Ballistic tip as .310.

Jon, I have made a copy of the ballisitics that you posted and I am very grateful to you for spending the time to put it up for me.
