I have loaded them quite a bit in both 30-06 and 308. They may come in little plastic bags, but lay moose, caribou and bear out in a hurry.
Have loaded them in the 300 Mags as well, after contacting Winchester and being told they work fine to 3000 fps, but have not used them on game yet.
They shoot very well, giving better accuracy then CoreLokts.
