Congrats!! It is always good to shoot a Big Hog, even if you can't eat them.
That is a very accurate bullet, at least in the 7mm's I shot it in.
I killed many a Whitetail with that bullet using 7mm mags. The bullet was a little soft for 7mag velocities, but I "lunged" them, which worked fine. It does not surprise me that the bullet made it to the spine & did the job. It also does not surprise me that the bullet did not exit, I saw that alot on Deer, much less Hogs. I just prefer a bullet that will exit in case I don't spine them or I don't break them down & they run a little ways. It sure makes them easier to find & especially in the dark. But no reason to doubt that it will kill a Hog.
Again, congrats!!!
