With a FFP scope, the reticle size changes with the magnification. This means that if using your reticle, 1 Mil (or 1 MOA) at 500y/m is still 1 Mil (or 1 MOA) not matter what the magnification is set to.
With a SFP scope on the other hand, the reticle appears the same size despite magnification changes. This means that if you are using your reticle, 1Mil (or 1 MOA) at 500y/m will NOT be the same at all magnifications.
This creates a problem when using a SFP scope for ranging objects using the reticle because it can ONLY be done at the scopes “true” magnification.
If you are ranging with your reticle at anything other than the scopes “true” magnification setting, your measurements will be incorrect and you will miss the target.
So…if using a SFP scope, you need to know the “true” magnification setting (usually found in the manual) AND ensure that you are at that setting when using the ranging exercises covered later in this book.
FYI…this also applies to leads when shooting moving targets. If you ascertain your leads at a certain magnification setting, they will only work at that magnification setting.
