4. g your trajectory pre plan all your targets and write in the suggestions of the ballistic program Log the actual elevation setting directly below It makes for a very efficient shooting sessions and gives you structured quality notes for your ballistic afterwork We always verify our rifle trajectories this way we never trust ballistic programs without verifications We always click the scope to record accurate settings and not perceived scope holdovers TH THLR NO THLR RANGECARD 5 Reticle holdover plan The letters A B C D corresponds to points A B C D found in the Columns for exclude the task of clicking your scope turret Usually a scope setting other than your zero is more useful when wathing an area Example If your primary target area is range 400 to 450 meters away then leaving the scope zeroed for 100 meters is just stupid You set it to 425 in order to have the shortest possible response time to targets appearing here Ifa fleeting target suddenly appears a longer range a quick shot by holding over with the scope reticle can be difficult Your holdover data is referenced to your normal zero Your options are using holdovers with reduced accuracy or using time and possibly not getting the shot off in time to click the scope e If you pre plan and plot these scenarios you can have effetive scope setting and at the same time have quick accurate holdovers A target in area C can be accurately shot with ho
