I think I might need to build me a 10- 12 pistol braced Grendel.

The performance of the 6.5 grendel per the above table is impressive - I’m particularly impressed with the performance at 16 inches, however, I entered similar info into StrelokPro (using the hornady 123 sst from the cartridge database)and it shows the bullet going subsonic at between 850 and 900 yards. Am I doing something wrong?
