I have been using the 168tsx since 2004 in my 300 wsm
. I have taken Elk, bear, mule deer, whitetail, and pronghorn. On elk it has always performed very very well with great penetration but I have never tried to anchor an elk with it through the shoulder blades.
I have several spent bullets around I have pulled from a hump on the far side of the elk under the skin that look like it came from an advertisement. But 168's are not magic and 180's,200's etc. will deliver more energy and bone crunching performance.
The 168's worked great in my platform to the point I haven't even switched to the tipped version just because I have all my dope down and don't want to fix what isn't broke.
