All rifles used to compete in the NRL Hunter series shall meet a minimum power factor requirement, unless excluded below. Minimum Power Factor (PF) is 380,000 and calculated by taking the Bullet Weight in (gr) multiplied by Muzzle Velocity in (fps). For example, 143 gr @ 2670 fps = 381,810 and makes the minimum. With a Muzzle Velocity maximum of 3275 fps 6mm with 115gr will not be able to make the minimum PF.As I'm a non competitive shooter i have a question....what is meant by establishing a power factor. Very interested in trying this out
Use of factory sealed box ammunition, .264" (6.5mm) and 130gr or above, is not subject to meeting the PF requirement under this section
I just pasted this from the rules section on NRLHunter.org
Lots of good info there!
