Anyone know whats the difference between the FP and RN bullets in 9mm?

FP= flat point
RN= round nose

HERE is a good link describing the terminal effects between the two

<edit to add>
FP can also mean full-patch, but that's an old-school term rarely used anymore to describe full-metal jacket bullets

You can not seat the FP bullet to the RN bullet COL as it will contact the lands and may not fully chamber. You have to use the COL for a flat nosed bullet.
