I also tried some 55 gr Blitz Kings in my 223 Mod 7 Rem when out with the 250, 25grs of BM2 with that bullet got 3150 fps which surprised me as other projectiles with that charge of powder generally go about 3040 fps. Point of impact was the same as the Hornady's it's sighted in for and they went into 29 mm group which probably could be improved on.
