PB's especially the lighter ones are known to fragment if pushed by a decent load, there are ways to elevate that problem but due to the fact that they are the most over priced bullet on the market why bother?
Sabots on the other hand have a wide range of bullets pushed faster with a better BC and SD so the shoot much flatter.
If you must have a conical try the Hornady FPB.
Look up the history of lawsuits against CVA before you deceide to believe all they say.
