Found a nice node at 3148 fps/ES 14/SD 7. Using the 175 ELDX, 26 Nosler case, 78.4gr Retumbo, CCI-250. I'm happy with this load out. I pushed it faster at 3200 fps and then I got a 3229 fps and that bullet was sight unseen at the target?! Pretty sure it burned up on entry?! I chambered my barrel with headspace gauges on the minimum and I'm at around 100 -125 rounds fired so far.How did your testing pan out?
