Since I'm curious about any real or imagined benefit to this cartridge over the 300BLK and since it does not appear that anyone has any personal feedback I'll see if I can't find a 12.5in barrel. I already have a 300BLK in this length so I can shoot side by side. I should also be able to try both cartridges on paper at 100 yards and on steel at 300 yards.

Supposedly quieter than 300BLK in subsonic use.
Higher velocity with lighter bullets than 300BLK in supersonic use.
