I'm totally confused here so bear with me and ask for better wording if I need too. okay so if I have a second focal plane scope (vx6 4-24x52) with an moa reticle, it's the leupold tmoa reticle, at what magnification are those elvation and wind age ticks correct? And with the CDS system, if I have it zeroed at 300 yards at 24 power, then reduce the power to 12 does my zero change? If I have the CDS turret, a zero at 300 at 24 power, and I adjust the CDS to a 400 yard mark but have the scope at 12 power will it still work?? Sorry again for the questions I've tried to rack my brain around it and just keep confusing myself more. Any programs that will help me learn or figure different figures for a range card?

Leopold has a ballistics manual for their scopes you can download. Looks like your reticles starts on page 64 As to your first question - Max power (24) |

Quoted: Zero should not change with a magnification change. Sometimes they still do. You might want to confirm it shoots the the same POI at min and max. I don't really use the mil dots unless I don't have time to range and dial. So I'm not worried about keeping those correct throughout the magnification of the scope. I'm just wonder that if my scope is zeroed at 300, a deer is at 500, I dial to 500 on the turret, and if I have the scope at 14 if it will hit the deer as I planned. Man this stuff is confusing  |

Poi shouldn't change with magnification change as stated. You should be able to test it at any distance.
Yes if you dial the scope to 400, it should be 400 yards(in the crosshairs) at any magnification. The only thing that really changes with magnification with sfp scopes is if you are doing holdovers. And that's a whole other conversation. I use strelok as an app of phone and putting in your rifle, scope and load info then using their reticle view feature really allows you to visualize how changes affect things in a sfp scope |

At what yardage should I check this at? The zeroed yardage or at various distances? I don't really use the mil dots unless I don't have time to range and dial.

I'm just wonder that if my scope is zeroed at 300, a deer is at 500, I dial to 500 on the turret, and if I have the scope at 14 if it will hit the deer as I planned. Man this stuff is confusing

Get the Strelok+ Pro ballistic software. It has your scope and reticle in its list. Put in your load data - muzzle velocity, bullet ballistic coefficient and other stuff, and your chosen zero. It will develop a load drop and windage hold off chart. It also generates a through the scope reticle view that shows the yardsge for each reticle mark (subtension) and a sliding scale for your zoom range up to 24x and down to 6x. When you change that slider position, it automatically changes the yardage numbers by each subtension mark. You will see that zero does not change, but holdover value and holdoff value for each other mark does. Your CDS turret values will only be correct for one specific load and with the zeroeupold specifies. But if it is correct it works at any magnification. Setting holdover with your elevation turret, called dialing for range, is completely independent of whether your scope is FFP or SFP or what its magnification is. |
