Impact velocity was estimated to be 2,600 fps at the range it was shot, which calculates out to approximately 2,700 ft-lbs of muzzle energy.Īsk any proponent of energy to define how it enables a bullet to kill game, and he will respond in vague terms. But what is energy? Is it definable? Is it measurable? This hole in the ribcage of a bull elk was produced by a 180-grain TSX from a. Energy has been utilized to rate the lethality of cartridges/loads for some time now. Gun magazine articles talk endlessly about the energy of hunting cartridges, and books about hunting are filled with references to energy as a determinant of effectiveness. After all, ammo boxes are stamped with energy figures, and ammunition retail websites offer ballistic comparisons between cartridges, with muzzle energy as the comparative figure. The fact that I am referring to energy as a myth flies in the face of conventional wisdom. According to Prasac, when conventional wisdom is repeated so often as to become law, rarely is that piece of wisdom challenged. In his new book, Big-Bore Revolvers, Max Prasac looks at terminal ballistics from the perspective of the big-bore revolver, and dispenses some of the myths he says are frequently perpetuated by the hunting/gun magazine industry as a whole. Rifle Sight Correction Angles: Computes the Minutes of Angle corrections for rifle sights.The topic of terminal ballistics is normally addressed from the perspective of rifle ballistics.Cost per Round: cost per round of ammunition based on the cost of a container of cartridges and the number of rounds in the container.Recoil Velocity of a Gun: computes the velocity at which a gun will move in the opposite direction in relation to the projectile that it fired.Muzzle Energy of a Projectile: calculate the kinetic energy in a bullet immediately after leaving the barrel given the bullet's mass and velocity.Ballistic Coefficient: factor representing the effect of air resistance on a ballistic projectile. Ballistic Range: computes the maximum range (horizontal distance) traveled by an object based on the initial velocity (V) of the object, and angle of launch (α), the launch point's height (h) above the plane.Greenhill Formula for Optimal Rifling Twist Rate: calculate the optimal barrel twist rate for stabilizing a bullet's flight given the bullet's diameter(D), length(L), specific gravity (SG) and velocity(V).Taylor Knock-out Factor: Calculates a factor indicating the power of a round.
