Big bore not required...
Should have seen the hog a buddy of mine shot this past weekend w/ a 22-250. This hog was shot at 127 yards...Per Bushnell Yardage Pro 500. The hog was shot in the shoulder...Smack in the middle of the shoulder w/ a 55 gr. Sierra Spitzer Boat tail. Blew a huge hole through the shoulder blade, and pulverized the heart/lung area. The scale indicated this hog field dressed at 161 lbs. I'm using mine this weekend, and hope to post some pics of damage done.
BTW...This hog was dropped dead in his tracks. No tracking necessary.
