I have used Kosher salt and Sea salt for beacon, Both turned out beacon a bit too salty for our taste. We tried pickling salt, it worked. We have done over 100# of belly beacon the fall and everyone has gave a excellent review.
That’s a big hog inbeed. I took a 285lb bore in SC several years ago. It wasn’t worth the processing fee . The smell when being cooker was very unpleasant taste was the same. What was left feed the opossums
