How do i change the DOPE value for a particular range on BallisticsARC?

[want2learn]

Hi, new to this.

I just plugged in the factory values for my rifle and scope height over bore as well as the data for the factory projectile into BallisticsARC (they didn't have my Sig Tango 6 3-18x reticle). I don't have a chronograph but found a couple of velocity values on line and they all seem to quote the same number of 2690 FPS....i know my barrel might not run at that value but that's all i have to go with now and i do know my come up dope at both my zero of 100 yards and the subsequently shooting at 300 yards.

I zero'd the rifle for 100 yards using factory Lapua 139gn load.

I then shot 300 yards (it's the longest range distance available to me) and found i needed 1.1 MRAD adjustment up to hit bullseye.

When i look at the program it says i should come up to 1.2 MRAD.

I know there must be a way to reset it to my 1.1 value but not sure how to do so...would appreciate the help. thank you

For something that close, just increase your velocity a little until it lines up with 1.1.

You really need more data points and longer ranges to properly true your software.
