Hornady 4Dof works pretty good. You already have Applied Balistics though so run with it, everything that app spits out initially is a baseline. I’m going to go on a tangent here, the BC that your bullet is given on the box is dependent on the rifle they tested it, it is not going to be exactly the same for you. So back on track, you need to true that muzzle velocity and BC. Step one is do you have a chronograph that works well (Labradar or magnetospeed) if not it isn’t the end of the world. If you do enter the speed it spits out for an average of five rounds. Next up zero for 100 yards. Then go out to 300 and get a group inside a 4” aiming point. Once you have adjusted for 300 take your data and check it to the chart AB spit out (set wind to zero). If it lines up 100% go further out, if it doesn’t change your VELOCITY. Example: AB says dial 3.8 MOA and you actually dialed 3.9, adjust the speed in AB until it lines up. Next go out to 500-600 and do this again. At this point your going to have pretty close dope out to 1,000 (side note 168s have a bitch of a time getting to a grand, try 175s) once you go beyond 600 yards adjust your entered Ballistic Coefficient and leave the velocity alone.
Hope this makes sense.
