The first elk I killed in the 70s I was using a 280 shooting 175 SGK's, and last fall took a large mule deer at 580 yds with the same 175 grain bullet out of a 7 mag. The bullet hit the deer at an angle, penetrated three feet of meat and grass filled gut leaving a fist sized exit hole.

I wouldn't hesitate to hunt heavy for caliber SGK's in 7mm/175 and 30/200 for a trophy elk hunt. In fact, I've gone to them of recent, for all my shooting in a 300 WSM and 7 Rem Mag. Great accuracy, good BC's and perform just short of Partitions in dry media test I've done.
