Mossberg predator 556

[papaboomboom]

Took my new predator out for first time today, mounted sig romeo 5 red dot, first time with rifle and shooting red dot, I measured the reported 9" twist and got 8.5 " twist, so I tried 77gr black hills hp....DAMN! This Turkey shoots, sighted in at 50 with 10 shots in tiny cluster, moved to 100 yes and it held group, having never used red dot, I am extremely optimistic about how it shoots with an 18inche barrel too. Anyone else have a predator?
