Bob, most of the guy's on here know me for Running Hog Dog's for 50+yrs and have cut many hogthroat's, but over the years have killed them with Handguns, .22 Rifles, Shot Gun 00,Shotgun Slugs, Shotgun Sabot's and numerous Rifle calibers.
You are asking about shotguns........Well, down here in the South, many hunters still use 00 andFoster styleSlugs which I also used in the early years. In the later yearswhen I decided to stalk for them, I switched to Winchester BRI's and Hornady Sabots. I bought a HastingsFully Rifled Barrel for my FN BRN A-5 12ga.
For 30+yrs I had my own 200yd range here on my place untill the county made me stop shootting cause of the close by subdivisions.[:'(]Well, I could bust burned out flood light bulbs at 125+ yds with rifle sights on the Hastings barrel andWinchester BRI's.....
