The older solid hardcast bullets work, as do many of the lswc designs. If idea of these bullets being that they make a good sized hole through and through, have enough weight to break bone and leave a good blood trail if necessary. The idea is over 200 years old and they do work.
Now modern bullets like the Barnes and the DPX have the weight needed and the penetration and they tend to expand. If for some reason they do not expand they act as a lswchp and plow through to the other side the same as the above.
30 years ago the jhp hunting rounds may not have penetrated deeply enough, or they may have broken up before penetrating deep enough, but those days are no longer.
The answer to the worrying is that a good expanding bullet of modern design will do all the older hardcasts did plus expand. What's not to like?
