Does anyone know of an app or can help me estimate projected drops at longer distances. I do not have a chronograph at this time and tired of wasting ammo trying to figure out dope for varying yardages. I’m currently shooting Berger vld target 140 gr pills with 39.3 grains of H4350. At 500 yards I am dialed in at 10 MOA up, at 600 yards I’m dialed in at 14 MOA up, at 700 yards I’m dialed in at 18.5 MOA up, and at 800 yards I’m dialed in at 23.5 MOA up. I’m trying to figure out MOA needed for 900 yards and up and 100 yard increments. Any assistance is appreciated.
