Leupold VX-R Ballistic Firedot...BDC for .223?

Okay scope wizards, I need some help.

I'm pondering the purchase of a Leupold VX-R Ballistic Firedot (4-12x40) for my AR-15 (.223 rem). I will be using Hornady 55 gr. V-Max ammo (3240 fps).

My question is... If I zero this scope at 100 yds., what will the two hash marks below the center circle (red dot) represent? Will it be say 250 yds. at the top mark? And say 350 yds. at the bottom mark? Does anybody know?

I can't seem to find any information on it on the Leupold website. (Maybe I'm just overlooking it.)

I'm coming from the Nikon Spot-On (BDC reticle) world, where I simply input my variables and the program tells me what each circle represents. (I'm a simple-minded guy, so please don't overwhelm me with all the MOA numbers...LOL) Thanks!

Here's what I'm talking about...

It will depend on what power your scope is set at. All that info will be in the owners manual, even though most times it is set at the highest setting of the magnification range.

But what erikc838 says is true, because I promise you that you are NOT getting 3240fps, take published velocities with a HUUUUGE grain of salt.

If you have already verified your nikon all you need to do is look at a grid measuring pattern at 100 yards and match the leupold to coordinates of the nikon. No ammo required to get close estimates for zero testing distances.
 
Here is a rough go by. Leupold ballistic drop scopes are set up for a 200 yard zero for ease of use.

So...

The first cirle is set up at 2.19 MOA from the cross-hair, and the second circle is set up a 4.80 MOA from the cross-hair. Please note these MOA #'s are for the spacing on your scope, at the scopes highest power so 12X in your case.

If you zero for 200 yards (approximately 1.5" High at 100 yards), with your load as listed and not counting elevation, atmospheric conditions etc. Also assuming your actual load is going that has that velocity.

Theoretically (per hand calcs and use of a ballistic calculator) you should be within a half an inch (low) at 300 yards (to the first cirle) and within an inch and a half (low) at 400 yards using the second circle.

My recommendation would be adjust for a 200 yard zero and then shoot at 300 (first circle) and 400 yards (second circle) to verify your drops.

Good Luck!
