Hi all, I am new to the forum but have been coming here for some time. Two fellas I know bought the 6.8 mini and are getting 7/8" to 1.5" depending on ammo used with scoped rifles and no modifications. As far as I know, neither have started reloading 6.8 yet. I was so impressed I bought a new H-bar mini 30(identified by fillet in front of gas block), although not a true "heavy" barrel, the added weight around the gas block dampens enough vibration to make it an acceptable shooter. My 30 will hit a pop can every time at 50 yards offhand with iron sights and factory (.308dia. bullets)ammunition through a .310 bore. No doubt handloading the correct dia bullets will tighten groups considerably, if that's your thing. I haven't tried 100yds from the bench yet. Hope this helps.
