The 140 's are great for antelope or deer,but light for elk.I have kiiled quite a few elk with30 cal 180 gr Game Kings and 7mm mag in 160 gr Gmae Kings. That 270WSM is going to push that particular bullet faster than what it was designed for, even for deer or antelope.
It is not so much a bad bullet or poor design,it is pople just pushing thme too fast. They definietely were not designed for magnum velocities.
I too have jar full of them. Some with core apart, some a nice mushroom.Funny thing, they all came out of dead animals
