I was using a 223 AR for hogs for a while. It worked Ok, but not great. Finally I decided I needed something a bit more effective, and it came down to the 6.8 SPC and the 6.5 Grendel. I went with the Grendel since I had some of the reloading bits and pieces for it. I shoot the 123 gr SSTs these days, and they do a fine job knocking down hogs. Way better than the 223. The 95 gr V-Max worked on a few hogs too. At Grendel speed, they don’t seem to act like a varmint bullet, but I was neck shooting them, not shooting them in the chest.
