Wow that did some serious damage. I have used the 150 grain ones in my 30-06 and didn't quite get the same results you did. However, I was happy with them. I shot a very large doe at about 150 yards with mine and the doe dropped right there. Didn't move even a foot. Just fell over. When I rolled her over, it was a tiny entrance and exit wound. Almost like the bullet just flew right through the deer and didn't do much other than poke a hole right through the deer. However, like I said the deer feel right there so I can't complain. When skinning the deer I found very very minimal damage. It look on the inside like it did on the out side.
So it got the job done without ruining a bunch of meat.
They also are the only ammo I've found to be accurate in my rifle which is very picky. So needless to say, I really like the ammo.
