That's plenty for a hog, just hit them right. Their vitals are lower than on a deer, and their spine loops down further than it looks with a hunk of muscle above the neck. There are pictures on line that illustrate this. Just aim right in the middle of the boiler room and they'll usually drop. I saw usually as some of them are real tough SOB's and can seemingly shrug off a solid shot...Good watched a couple of these pig calling contests, And no way am I going that route
But back to Pigs sighting Zero at 150, using 165 gr. should be good?
