I found this video interesting regarding factory PRC ammo. Picked up a box of Federal this morning purely out of curiosity
Good video review, it's consistent with my chrony results through a 20" xbolt. I also found the Federal to be 100 to 125 fps faster with minimal accuracy difference. The Hornady 175s where the most accurate but also clocked 2726 whereas the Federal 175's came in 2843 avg.
testing loads now with h1000 and staball hd as rl26 is unobtainable these days.
