I don't know where you plan to shoot oinker's but where I shoot that is waaaay too much scope for hunting.
I'm shy about scopes for hunting. I have one on a 308 bolt gun, and I use it a lot, but only when I'm expecting to take that long shot. Most pig hunts I still use an open sight lever gun.
For hunting purposes I would recommend a 1-4x, 2-7x, or 3-9x... And that really depends on how much range time you expect to be doing. My .308 bolt rifle has a 3-9x on it, because I use it in CO for 150+ yard shots. Except for one hunt in CO, all my shots with that rifle have been done at 3x or 4x. I regularly shoot it at ranges out to 300 with no issues. I truly believe you only need 3x per 100 yards. That would make your 6-18x scope ideal from 100-600 yards, but really difficult for shots closer than that.
As for my personal .308AR, I am shopping for the IOR Valdada "Spartan" 2-12x36. It is on the more expensive side of scopes, but I wanted a scope I could shoot from 50-300 yards with. I was going to get the NF 2-10x, but I like what the Valdada offers more.
