I know a second focal plane scope Usually have to be at max power for bdc reticles to work. But is it the same for dialing in ? Using a drop chart can you still dial in at any power?

dialing in at any distance will get you the same impact no matter what power you are on. The intersection of the crosshairs do no change like the distances between the BDC marks. If you are on 3X and dial in to make your hit at a distance you'd still dial in the same if you were on 9x or whatever. Changing power does not affect it.

The reticle turret adjustments are consistent at all power settings. The subtensions change in a second focal plane scope. (The reticle stays the same size and the viewed object increases with an increase in magnification.

Folks ain't got a sense of humor no more. They don't laugh they just get sore.
Need to follow the rules. Just hard to determine which set of rules to follow Now the rules have changed again. |

for a sfp scope to show the same poi at all powers the erector must work exactly the same way each time the power dial is turned, a near impossibility. it is inherent in the sfp design. this introduces a random error into the mix. The only company that I know that warranties no change of poi, because they have a stage for it in their quality control to check for it, is night force. They say they warranty against any change of impact, not that their isn't or could be a change of poi, a big difference. (yes we have no bananas). All it means that it wasn't observed during the time the inspector used it. The better the scope the more likely of not seeing a change of poi
