I used the 200g SMK on a big black bear out of my 300 RUM doing 3200fps. Shot was 200-250 yards and the bullet entered point of shoulder. It was pretty messy and the bullet did not exit. Instead I found it about 3/4 of the way through and the biggest piece I found weighed like 30g. Based on a shoulder shot perspective, I would not use the 200g SMK, maybe the 220g SMK. I was planning on using the 200g SMK for elk myself, but after that experience, I switched to the 200g AB and had great results with that bullet. I am a shoulder shooter so I need a somewhat tough bullet, not the toughest, but I dont need a bullet that loses that much weight when hitting bone. I'm sure things might have been different penetration wise if the range was 500+, but I took what I had.
