As to people's desire to shoot really light monometal bullets from 30 cals at very high velocity, good luck to people if that's what they like but... Why is that in any way better than a 180g cup and core bullet solution at more moderate speed?

Seems to me they'll probably both work about the same as far as killing quickly and humanely. Accuracy is likely also to be similar.

And while one will kick a bit less than the other, it will also cost about two-and-a-half times more.
