[QUOTE="jrock, post: 2913590, member: 78569"] Shooter or 4DOF are great low cost options. For most shooters shooting box ammo and wanting to start into longer range shooting: - Get a good zero at 100 yards - Use the box muzzle velocity and add or subtract 25 fps per inch of barrel length assuming the box value is based on 24" - Use an app to tell you the drop to 500, dial and shoot a good group. - Check the difference in drop and adjust velocity in the app to match the amount dialed. -Then set the turret to the correct drop for 500 and let the 100 yard zero fall where it may. Small error at 100 but a good zero at 500 gives people a lot of confidence. For more complicated shooting, I use a chrony as a QC/QA on my loads while I shoot for drops based on a true 100 yard zero.
