Between me and my buddies, we have killed over 300 pigs in last few years using 6.8 with AR Performance barrels and Hornady 120gr SST handloads.
Experience indicates that the SSTs are accurate as stink but not the best bullet for deer....
I have no experience with the 6.5 but like the round.
99 percent of my shots are under 200 yards.
If most of my shots were 200-300, I might look harder at the 6.5
That being said, with the right bullet, either would perform well.
If you have friends that use either caliber, think about going that way to make teething pains easier!
