Take it for what its worth, this is my data
500gr RNFP Gas Checked Lee Mold
16.8gr IMR Trail Boss
Seated to the last band
Roughly 1200fps
Right now I have some 240gr loaded with trailboss waiting to be shot, Im up to 19grs I can probably only get .5 more in the case then the powder will start being compress by this light bullet, I dont know what the fps is but its still groupin very good with no pressure signs and recoil is low. I suspect in the 1700fps range right now, but will have to dig out the chrony to confirm.
