That's too broad of a question.  They shoot great at higher speeds in some guns and lower speeds with others.  For example, my 30 Hercules shoot them at 1040 fps and they are still stable.  In my Ataman M2R I had it adjusted to shoot them at 930 fps and they were spiraling so I turned it down to 890 fps.
