I am looking to buy my first long range scope. Already have old Pentax Lightseeker 3.5-10x50 and I am very happy with glass and mechanics. So I thought to buy another one in 6-24 mag, 30mm tube that someone selling new for $400 on ebay. However, it has fine plex reticle. I wonder how usable it can be for long range applications. Pentax website lists two reticle choices for this model: mil dot and ballistic plex. This one could be old stock? Thank you
