So if you want to shoot stuff with 200gr + bullet weights at subsonic speeds, why not use a pistol cartridge?
Because they cannot use them in an AR15 platform. That is the sole selling point of the BO.
But quit complaining so loudly--the BO is causing the bullet makers to produce lots of fun 30 cal projectiles, and they all work well in the 308 and 30-06 too. Win-win!
