I just ordered a AR Performance 6.8 tx upper, and I got a POF lower from SOG Armory. I will be using it for hog hunting. And I would like any input on this round. Palmetto has the 6.8 Barnes 110 grain tsx combat loaded it should have a 2750FPS or do you thank the 85 grain Barnes tsx with 3100FPS would be better. Any input will help. Thanks Brian
