I have a Leupold VX 5 3-15x44. I will be putting it on a 7 prc in preparation for an elk hunt. I know I can get the CDS custom turret, that I would have to pay for as I already used the freebie. I would like input from experienced shooters to tell me if you like the CDS or would you just use the original turrets as is and just adjust based off of charts from an app. I sight in at sea level and then hunt at about 5,000 ft. I am thinking that I am better off with an app that I can input actual live conditions where I am hunting that day and make my adjustments. CDS just seems kind of ballparking the variables. FYI, I am also trying to get my 10 posts so I can list some guns in classified., so I appreciate your help.
