I am a wildlife biologist in South Texas. I have taken over 500 animals with a 130gr SMK fired out of my 7STW, 150+ of which were at >400 yards. I have never seen results like the SMK produces. I have loaded 160 accubonds, which tend to poke small holes without bone contact, 140 VLD's, 160 gamekings, and barnes ttsx. I originally loaded the SMK's for playing on hogs/coyotes in the offseason @ 500+, but after seeing the internal damage, I have stuck with them. Generally, the petals peel off leaving a "cigarette butt" that mushrooms and makes a large hole, while internal damage is brutal. Most of my blood trails, while short, look like you poorer blood from a bucket, and the heart/lungs look like they were run through a blender. My longest kills, 815 and 835 yds on consecutive shots, were a pair of does- one shoulder shot, one hit in front of the vitals low neck/ point of shoulder. Neither made it more than 30 yards because of fragments that contacted lung and significant muscle damage. The same load was used to take a 3/4 grown bison, shot through the shoulders and lodged under skin opposite side. The only negative is that at extremely close range, the 3,550 fps only makes a hole about the size of a golf ball and they will generally run 50 yds or so. That's alot in south Texas brush! I also load the SMK's in 308, 300 RUM, and 6.5 calibers with similar results.
