I built a 7 PRC for ELR. I had a Krieger barrel installed on it 32" long for more velocity. Using the Satterlee method accuracy node showed 3096 MV I was hoping for 3150. I am using RL 26 and ELD M 180 grain bullet. Charge is just 3 tenths above Hornady manual max weight load. Haven't got to bullet seating depth yet.
 
I had issues keeping the ELDM 180's together at over 3150.
I was running them from a 7X300WSM in a 7.75 twist barrel and had to keep it around 3050 The next node which I got it up too was 3225 and I blew two up in the barrel. If your only a 8 twist you might get away with it, just what happened to me.
