M193 has a proven record of inconsistent terminal performance. Barrier blind gives you the most consistent performance, including through common intermediate barriers.
The open tip of match bullets are a byproduct of manufacturing, not a design feature. The jacket can be made more consistently that way, so you see it in match bullets. None of the aerodynamic theories are correct.
Open tip match does fragment more consistently than FMJ, and is legal for military use. It is still not as consistent as expanding designs, so unless you are military I recommend a barrier blind load that meets FBI testing requirements.
