Give the Hornady 120gr SST a try. They have a high B.C. and are a known and proven killer of hogs and deer.
I have several one shot kills on hogs >250lbs from my 10.5" AR/6.8. These were factory loads but I have since duplicated the factory loads speed given the 10.5" bbl length.
From my 18" 6.8 I shoot a 85gr Barnes TSX @ just under 3100fps. This is my night time hunting gun using a thermal sight. If the hog action is slow we call coyotes. I want the extra speed and trajectory produced by the light,high speed bullet. These bullets kill the bigger hogs well also if put square on the shoulder. --- SAWMAN
