Don,
I do understand and agree with all of that, but I think your vocabulary needs some reconsideration. The point blank range or point blank range yards is where the projectile falls below the line of sight equal to the maximum trajectory, which can be adjusted, as you stated. There are many factors when considering the point blank range yards, error, probably being the most important. So, the user or shooter must decide what the maximum trajectory will be based on the size of his target, his skill and the shooting conditions. Since his opinions on these factors will be brought into the equation, I think the term “maximum point blank range” would be a personal decision more than a fact, and no table would point to this. I don’t have any literature in front of me, but based on my knowledge of shooting the following are the only measureables that would apply;
- Near zero or near zero range yards (the first time the projectile passes through the line of sight and it’s associated distance)
- Maximum trajectory or maximum trajectory range yards (the distance the projectile travels above the line of sight, and at what distance down range this occurs)
- Zero or zero range yards (the second time the projectile passes through the line of sight, and also at a given distance)
- Point blank range or point blank range yards (the distance in which the projectile has fallen below the line of sight equal to the maximum trajectory)
- Supplemental range or range yards (the distance in which the projectile has fallen below the line of sight equal to twice the maximum trajectory)

So, maximum point blank range does not fit into this shooting logic, not at least on it’s own, and I have never heard of that term, which is why I asked. Since this distance (maximum point blank range) would take personal opinions into consideration, I don’t think it merits any association with a viable shooting term.

Respectfully,
