What the heck it works for me !!
I have used JBM since I don't remember. More recently to evaluate the effectiveness of hunting bullet terminal velocity and especially performance in that regard. I cannot find JBM's definition or meaning of the term point blank range. The range is clearly illustrated from a run with a given velocity. I thought the main function of the term was to define a circular target area, or radius, and how far away a bullet would stay within that sight radius. Shoot within a tube. I thought that radius would be the vital zone of the target, or similar area. I can't find this definition of how big their MaxPBR is. I see my MaxPBR displayed in yards, I don't know how big that area is. anyone know ? - thanks
I can use their data run to determine a 4-inch high to 4-inch low distance. I understand that. I ask because they, their data run uses the term and I want to see what the size component is.
