Hello kuduae,

Thank you for the info.

Here is a shooting update. I custom loaded both 22 Hornet ammo and 11mm Mauser ammo. (loads are shown on the targets) I fired the right 11mm barrel first, followed by the 22 hornet barrel. I fired 5 shots each barrel to zero the scope. After the 22 Hornet barrel was zero at 50 yds, I fired a 3 shot group with the 11mm barrel that went into a 1 inch group. Although left-to-right was good, the 11mm group was 10 inches low.

And now I understand the reason for the Nikon Prostaff Scope. The reticle is BDC = "Bullet-Drop-Compesator" that consists of a series of small aiming circles, below center, along the vertical wire. These circles are for reference "hold-over" for various ranges beyond initial zero. The aiming method I used is shown to the right of the target pictured below. Although the aiming was different for the 2 calibers, its easy to remember and use when hunting.
