Anyone loading 6.5 PRC with bullets in the 140 - 143gr class using IMR 4955?
I saw the loading in Hammer thread on the 123gr looking for some data for heavier bullets.
 
I ran the 140 ELDM and the 143 ELDX in QL and came up with the attached. If you have a specific bullet in mind other than these, please let me know and I will run that for you. As always, start low and you assume all liability.

If u ran 26" barrel would it add about 40fps with the 143gr eldx?
