I bought mine new and it didn't have a manual enclosed, so you're not alone.I bought a used scope so it didn't come with an instruction manual and I haven't been able to find anything useful online apart from the zeroing and reticle pdfs. Does anyone know of any additional user manuals? For example I'm curious what the height elevation markings on the turret correspond to? One full turret turn equals 3 markings on my scope and I simply don't get it.
