In your last podcast you talked about how to thru your ballistics. Generally the experts say that 500 yards and under change the velocity over 500 yards change the BC. So at 600 I would change the BC rather than the velocity to correct
Not sure what experts those are or why they’d say that, but I’ve talked to the actual engineers of several of the most popular apps and they all said to change velocity.
If you don’t have a chronograph, I’d always change velocity to match. If you do have a chronograph, then you’d use the truing function itself.
