I have been shooting the 65 SGK in my 14.5"/556 AR pretty much exclusively for 3 years now. I shoot them for everything. Jackrabbits, coons, coyotes, hogs, deer. IMO they really are a do everything bullet at the velocity I am shooting them. I have had to shoot some coyotes twice due to shot placement, but that is on me. Mostly those were running shots. What has really impressed me is how well they work on hogs. Generally on pigs I would rather shoot my Grendel out night hunting. But if you put that 65 SGK in a solid location, it will flat put pigs down. If I happen to have the 556 with me and not my Grendel when I run up on some hogs I do not feel disadvantaged, I just know I need to be a little more concentrated on shot placement.
I do think the front of that 65 is fairly soft. It seems to me the initial upset is pretty quick. The front expands and starts causing damage early. Yet at the speed I am shooting them the base section holds together and gives good penetration. I have seen them go clean through medium size (125-150 lb) pigs, broadside through the shoulders. Here a while back I shot a 150 lb boar in the face (through the eye) and found what was left of the the bullet in the chest cavity. Also last spring I killed a coyote with the same load, it was sitting facing me at 275 yards. One shot and it just rolled over and died right there.
I trust that 65 SGK. Does everything I ask of it. That says a lot in a small caliber bullet.
This is a sounder of pigs I walked up on at night with my Thermal. I was by myself, no backup shooter. I ended up killing 5 pigs with hits on a couple more. This was with my 556 and the 65 SGK. I had to spin around looking for hogs because I could hear them running past me in the dark.
