I figured those speeds were coming from N570, I have plenty of Retumbo and H1000 I plan to use. Also have 5lbs of RL26 but have so much confidence in H1000 for every rifle it’s feeds.82.7gr N570 with the .308 196.5gr BD in a 30-8x68S Improved. Case capacity is identical to the 30SM.
CCI250 primers with bullets seated 0.035" off the lands.
MV ~3,140 fps from a 26" barrel.
