Why would a slow twist in the barrel of a gun make it shoot round balls better than conicals?

Conicals are longer and much heavier and need a faster twist in order to stabilize. This is a relative thing. A twist like one turn in 32 inches just might shoot both round balls and conicals well.

Not only twist but length of barrel are important in these calculations.

COMMONLY, it is stated that /48 is the half way point. anything faster is conical, anything slower is round ball.

I have a special Rice barrel, its 1/60 @ 42 inches. I shoot only roundball, and they do go a long ways.
