Premium boolits have definitely changed the rules.....
In all honesty, I don't think premiums (as in new super premiums) have changed the rules all that much. The good ol Win power points and other standard soft points did well for deer and antelope when I first was of age to hunt in the 90s. I killed a few pronghorns and deer back in high school with a .22-250 and had similar results to those pics posted above. Soft points at 223 velocities may have been different. I don't know.
