Many shooters attempt to create hit data (Data On Prior Engagement) utilizing a ballistic chart of pre-printed data points based on the basic ballistic solver parameter inputs; bullet diameter, bullet weight, muzzle velocity, ballistic coefficient, yada yada yada. I get it. It can be done, but it is neither predictable nor repeatable because you are working the problem from the wrong end. Don’t start with solutions. Start with problems.
A classroom full of eager students sits bright-eyed on Day One of Precision Rifle One. Theories and terms are bouncing off the walls. Some are innovative, cutting edge and some have been around since our Granddad took us on our first squirrel hunt. But they are all relevant. Especially those that have been pounded into us but we never took the time to fully understand, like “Parallax”. Got it. Heard it mentioned a thousand times and pretty sure I’ve got it figured out… but do you? We move to the range to do some scope tracking and half the class experiences parallax for the very first time. That is when the light truly comes on.
