I got a chance last year with a 2fer1 shot....but I didn't plan it or even know it when I took the shot. I was going out to fill up my feeder at about 230 in the afternoon. I walked up with my ruger 44 carbine ready and saw a nice 70 lb porker. His head was down slowly checking the ground for food. I placed the Red Dot scope just under his ear and touched off a round. Pig went down and started the "twitch". However I looked and counted 8 legs twitching!
Upon checking I discovered that the 70 pounder had his little brother (55 lb) feeding right beside him.
The 44 slug went through just below the ear on both pigs!. Some days you just get lucky!..
