I've used the Cutting edge 160 for two seasons now in my 7 rem mag. They are the most accurate bullets I've shot in this rifle hands down. I quickly came up with a very accurate load using only 12 bullets for load development. I later played with another powder to get more velocity. Every load I have tried with these bullets have been under 1 MOA at 330 yards. My rem mag will get these just over 3100fps with Retumbo.
As far as on game performance, I have killed 3 deer and an antelope with these. I started loading them to use as an elk bullet, but less time to hunt the last two years has kept me from testing on elk. The first thing I shot with them was a buck antelope at about 200 yards. It was facing me straight on and slightly downhill and I shot him in the center of the chest. Bullet exited his belly a few inches behind the end of rib cage and hit his left quad and exited the back of his hamstring.
Next was a big, tough muley buck at 280 yards. First shot entered just behind front shoulder and exited opposite shoulder. He did not go down so I shot again. Second shot hit within an inch of the first. This shot put him down but his head was still up and he was angled away from me quite a bit, I put one more in him. This bullet was recovered in the opposite hide of his neck. It weighed 141 grains.
This year I shot a muley doe at 402 yards. It was behind the shoulder and exited, killing her instantly. Also got a whitetail buck this year at 210 yards. Lung shot, exited took a little while for him to expire.
I am happy with the performance of these, but I think they are a little tough for thin skinned animals like deer and antelope. I usually get quicker kills with a more fragile bullet. I think they would be awesome for elk, which is what I got them for but wanted to test on game. I would like to try the new 155 grains as they have a higher BC. I could also get more velocity out of them which would probably improve game performance.
