To build a 6.8 SPC or stick with 6X45?

[Russ]

I have been reading about the 6.8 SPC and it has peak my interest for a new AR build. I currently have a 6x45mm and it's a tack driver and has killed numerous hogs. I not sure if I would be gaining much over the 6X45 with the 6.8 SPC. Suggestions?

Good question. I have built two 6.8s and a 25-45 Sharps and am still wanting to build a 6x45. Unfortunately, a cratered diesel farm truck has settled any question of "next caliber" so I don't have to worry about that for a while.
