[QUOTE="memtb, post: 1540807, member: 75451"] While it is true that SD in it’s primary form was to predict a solid bullets performance on a game animal..... it could still be somewhat relevant with expanding bullets. Mass determines a bullets ability to continue in it’s directed path. If a bullet expands, the SD will be altered, with lowering of it’s SD. The greater it’s frontal area, the lower the SD. The higher percentage of the bullet weight retained, the greater the mass is retained. The greater the mass retained, as previously stated, helps the projectile continue forward. Conversely, a bullet of high SD, but shedding a high percentage of it’s weight (mass) after impact will sacrifice it’s ability to continue in it’s directed path (penetration). As shooters/hunters/sportsman, it is our duty to determine what the intended purpose of the bullet is. For target use, whether short or long range, bullet integrity (ability to retain weight or mass, after impact) is irrelevant. For hunters, it is our responsibility to determine the intended uses for our bullet. If extended ranges, for small, relatively light-boned big game is the intended use....a high BC bullet (high SD) bullet offering violent expansion and high percentage bullet weight loss(mass) is acceptable. However, that’s a narrow “bullet use” parameter. If larger, more heavily built game is the goal, the ethical hunter, may have to sacrifice some bullet BC in order to have a bullet that may have the same or similar SD, but retain a greater percentage of it’s mass due to the structural integrity of the bullet. Which coincidentally widens the “use parameters”, due it it’s ability to retain it’s mass on a close range, high velocity impact. JMO. memtb [/QUOTE]
