Thread: Long Range Shooting and TBR

Beyond that you can either enter the line-of-sight distance and an angle, or simply the TBR / EHR value on it's own (it is already corrected for angle).

@Pommy, most ballistic solvers are time of flight based. Time of flight is pretty much identical whether you fire a shot at 0 degrees, 45 degrees, or straight down a vertical mine-shaft. But there is a significant difference in the amount of elevation you would need for each of those 3 shots. When I teach people about incline shooting, I've found it often takes them thinking about firing a shot straight down before they really start understanding the concept.

When I did some ballistic calcs and compared bullet drops (in inches) using the line-of-sight distance/angle inputs against TBR/EHR on its own I found huge differences at longer ranges?
