Do you remember how long it was supposed to take to “flatten the curve”? Weeks not years. In this article, it takes a second or less to flatten the curve.
To flatten the curve for hunting deer, we will follow the science. No masks required. This is primarily the science of external ballistics with a nod to terminal ballistics. The curve is the trajectory or arcing line of flight that a bullet takes when it leaves the muzzle of a firearm on its way to a down-range target. Because the barrel is pointed slightly above the line of sight, the bullet rises as it leaves the barrel at its muzzle velocity. As the friction of moving through air and gravity act on the bullet, velocity slows, and the bullet’s trajectory turns down. The decrease in velocity and the shape of the trajectory can be predicted taking account of variables like muzzle velocity, weight and shape of the bullet as well as the relative density of the air measured by height above sea level, local temperature, humidity, and barometric pressure.
This is important because:
• You get really excited, and your pulse races when you aim at a deer (buck fever).
• Your rifle hurts every time you pull the trigger (magnum rifle).
• It’s hard to get a deer to stand broadside at exactly 100 yards (real world).
• Your buddies at work set up a pool on the success (or failure) of your hunt. (ego)
• You spent a lot of money on gear for your deer hunt (anxiety).
Whether you accept the multiple challenges of a deer hunt with your personal defense rifle or your favorite hunting rifle, a basic understanding of the ballistics of the cartridge you are using will allow you to focus on only one point on a deer’s anatomy regardless whether your target is at 50 yards or 200 yards. Seeing a deer at 200 yards or less, knowing exactly where to aim, and knowing from practice with your rifle how to gently squeeze off a shot is what it takes to have a freezer full of venison. This basic concept is called Maximum Point Blank Range or MPBR. The distance in yards is derived from the external ballistic data for a given cartridge. We will come back to this very useful tool, below.Continue reading“Flatten The Curve for Hunting Deer – Part 1, by Behind The Counter”
