GameKings have worked great for me on elk and mule deer. Great penetration and exit holes.

My last kill was a large mule deer at 580 yards. The 7mm 175 GK hit him in the front and penetrated
all the way through him including his gut, bullet entered the front left shoulder and exited his right ham.

I wouldn't hesitate to use them (heavy for caliber) on a trophy bull elk hunt.
