[QUOTE="Barbourcreek, post: 2904403, member: 124432"] Thanks for the reply All bullets work a little different This is a general rule that cup and core bullets (lead core copper jackets) will expand at a minimum retained velocities of 1600 fps left on impact on an animal I base this discussion on experience and testing Retained velocity also is different at different station pressure or elevations Rotational rpms left to stabilize the bullet is used to make sure the bullet is stable near transonic, we dont hunt in transonic but it guarantees stabilization at mach 1.4 - hunting distance or velocity. This is why we use a stability factor 1.6 minimum is my guidelines for my students [/QUOTE]
