Crazy Carl, helping answer your question by reposting an answer from above that was buried in another post:

(I'm) using 165grn hornady SST with 43 grns imr 4064 I think . So far so good not many get away ….. had one run about 150 yards, thought I missed but a week later my nose found it, it was moving so I guess I hit it farther back, try to head or neck shoot them. I don’t have a thermal so have to rely on moon or gun mounted hog lite
