Practical D.O.P.E. for Long-Range Rifle Shooting

By Woody published on in Safety and Training, Videos

Do you gather and organize D.O.P.E. (Data On Previous Engagements) to improve your long-range rifle shooting? In this National Shooting Sports Foundation video, Ryan Cleckner discusses what information to gather and how to make it handy enough to access under any shooting conditions. The goal of D.O.P.E. is to allow you to repeat previous performances when you shoot.

1:15 Discussion of ballistic data available on ammo boxes and how to use it to get started.

2:15 How and why to use a preprinted D.O.P.E. book and it’s limitations.

3:10 How to store and use index cards to collect D.O.P.E.

3:30 Why a contractor’s pencil is invaluable for writing down information reliably.

4:00 How to use a manufacturer’s bullet-drop compensator and how to make your own.

4:30 How to use masking tape to place D.O.P.E. inside your scope cover.

5:05 Features of a Retractable Ballistic Tape.

    Flick: We all do so don’t sweat the petty stuff, I wish that had an editorial feature like some blogs do that let you correct the screw ups we missed the first time. It’s the thought that usually counts.
