I have a 18" barrel but am trying to get into a longer barrel to extract the most potential out of the Grendel. If I can't does the 18" barrel provide enough velocity to set the Grendel apart? I have a 6.8 for hunting under 250 but want the Grendel for longer shots. Will the 18" let the Grendel shine past 300 yds?
