It was an interesting mathematical equation using rifles, bullets, pigs, and angles.
Before we get to the video lets just look at the hog who was doubled up on standing behind/next to the hog who was hit first.
That's a 308 hole in the side which would have been the exiting 165 grain projectile from his buddy and a 6.5mm fragmentation on his head/ear which would have been the 90 grain TNT coming apart.
Let's take a closer look at that head shot
There are at least 6 small holes from the shards of jacket/core that impacted this hog.
So that is 2 shots (1 a piece from each shooter) simultaneously on a front pig (not pictured) and a bystander making a total of 4 holes.
And then it got more interesting, as we found out a third pig had actually taken a hit with these opening shots so what is that a double-double-single?
Just watch the video...
