Faster is not always better.
Rounds traveling too fast may pass through the pin and not pull it down. It is my understanding that FMJs in a .223 might do this.
I would not over think this. As I and others have said just go and have fun. Everyone I have encountered shooting pins, plate, or other activites at the MRA have been great.
A quick search online shows that a power factor of 210 seems to be what most are trying to obtain.
