Schmidt & Bender Precision Hunter rifle scopes are based upon three of Schmidt Bender's our most popular Classic series scopes, each equipped with a top-mounted bullet drop compensator and reticles designed to let you place an accurate shot at long ranges. The elevation adjustment knob on the Precision Hunter has graduations and numbers that allow you to create a custom distance chart for your preferred caliber. Blank elevation rings are also available with markings you can record after sighting in your rifle. All Precision Hunter scopes have 30mm tubes.
The reticle on the Precision Hunter is the "P3" or mil-dot. Originally designed for military and tactical use, the mil-dots can be used for estimating holdover at longer distances, as well as for windage allowance and for leading moving targets. The P3 allows very precise rangefinding.
You might want to go over to the Sniper's Hide web site. Do a search there and post your question. Those shooters are into S&B. I have not used one yet. Well respected. It is my understanding they are built for playing with the turrets, excellent tracking. Great glass.
