Thanks for the info, but why woudl I want to use this target wadcutter for SD? Shouldn't I be using a hollow point?
The reason someone might choose a wadcutter is consistent performance. At low velocities or through heavy clothing, some hollow points don't expand when fired from a snubby. If a hollow point doesn't expand, it acts like round nose bullet. A wadcutter offers slightly more tissue damage than a round nose bullet and it won't be clogged with clothing.
There are several hollow point plus p rounds that offer good performance in the .38 special but there are only a few good standard pressure hollow points. Someone limited to standard pressure .38 Special could do worse than choosing a wadcutter for their snubby.
