i have a 18" barrel and the ammo's fps is 2850, i think.
so i am hoping for another 50-75 fps the the extra 2" of barrel.

the (excel) software i have has some constants that i have mod-ed with the things i know for 110 grain 6.8 ammo and 5.56 ammo. so i do know the software is allways to fast and too flat for the 6.8 but i think i have it with-in 10%

It is supposed to shoot at 2900fps from a 16" barrel. But we shoot an 80gr .223 Sierra bullet, so 90gr for 6.8 is kinda
short and fat, so I don't know how long before it goes subsonic. I would think it would bleed speed quicker than heavier
6.8 bullets. But, I really have no idea.
