No scope, no matter what the manufacturers want you to believe, can have pre-determined marks following a zero. Too many variables for that to happen. You have to find the load your rifle is most accurate with to zero in the main cross-hairs and then find the distance for each additional dot or circle your scope has. And yes, with most BDC ret. scopes, your magnification will change your zero on the additional dots or circles. Not on ALL of them but most of them. I am not personally familiar with that scope so I don't know if it is one that mag will change them or not. I'm also unsure on whether that is an SFP or FFP scope so that could be an issue as well if it is a cheaper made scope. The best thing you can do is test it out at different magnifications and different ranges. Put it through it's paces.
