![]() I will also assume an elevation of 3,500 feet above sea level, and an ambient temperature of 15° C. I will not adjust for target deceleration – I will presume that the target will maintain its speed of 45 mph throughout the shot. For the purposes of this discussion, I will use a standard of a regular clay target, travelling at 45 miles per hour.Another way to look at it is how far the target will move in the time it takes for the shot to transit the space between the target and the muzzle of the shotgun. I hope that most people would agree that lead is the distance in front of the target, along the line of the target, that the shotgun must be positioned if the target is to be broken with the shot. Another point that we should be in agreement on is the definition of lead, or forward allowance.That is to say that a target flying across the shooter’s field of view will require more lead than any other target that is either angling toward the shooter or away from the shooter. ![]() One important point that should not be in dispute is the fact that with all other factors being equal, a target flying perpendicular to the shot will require the most lead.What does the science tell us?īefore we get too far into this discussion, it will be beneficial to agree on a few specific points. There are almost certainly more questions, but these are the ones that I am most familiar with. Are the composition and dimensions of the shot in the shell important?.Is muzzle velocity the most important determinant when considering long-range performance of a shotgun shell?.If I shoot a faster round, will it reduce my lead required to break a target, especially on targets at longer range?.The main principles that I hope to address in this piece are: I will caution you now, if you are not into numbers and little bits of physics, this article is likely not for you. I hope to shed some light on some of the more commonly held beliefs and hopefully provide people involved in this great sport with some additional information, and thereby enable them to make informed decisions regarding their ammunition purchases. Rather than go through some of the more common theories, I thought I would approach this from more of a scientific perspective and include a sprinkling of personal experiences that appear to be relevant. Not everyone puts a lot of thought into it, but some do, and some apparently put a whole lot of thought into this topic. One does not have to spend a lot of time on the shotgun range or in the clubhouse to hear someone’s theories on the velocity of their shotgun cartridges.
