So with 124gr RMR Match Winner bullets loaded at 1.095 I am getting a power factor of about 126-127 with 4.3 grs of N320. Too close for me to take a chance at crono. That was from a 4.7 inch Grey Guns slide in a Sig 320.
I was planning on bumping it up to 4.4 Gr, but the VV lists the max as 4.3. Has anyone had an issue going to 4.4. I saw no pressure signs at 4.3, but figured I would ask here before actually doing it. Thanks
