Lost a bull elk when the 175-grain Interlock from my 7mm Rem Mag came apart on his shoulder. Looked unsuccessfully for a day and a half. The shrapnel did enough damage that he died, though. We finally found him three days later, a mile or more away, thanks to the flock of ravens that were pecking away on him in the blow-down where he had crawled in and expired. I have never tried another shoulder shot on an elk.
