I would think at some distance the cphp would flip back around, simply because the drag is going to be so high. I base this on basically nothing other than idle speculation.Can you get good groups with them backwards?
I shot sparrows a lot with flipped CPHP. They worked well enough for 10-15 yards. And they tore some sparrows clean in half!
