I used the follow load for my 9mm rounds 4.3 gr. of W231 in my 115 gr. RN Rainer bullets and was getting 950 fps. Then I started working my loads up and found that 5.1 gr. was coming out at 1100 fps and 5.3 gr. were 1150 fps. on the chrony.
Has anyone else found this to be the same results?
Bullets: 115gr Raniner RN
