Tell me why buying a Rifle chambered in 6MM Remington is stupid

[Cam Moon]

I only lost one moose with my 6mm. And that was MY fault. I still say it's incredibly underrated.
On a side note, with the grizzly talk above, what do you guys think the required energy is required for such a beast? (NO, I'm NOT considering a 6mm!!!)

As far as Alaskan brown bears go (it's not been legal to hunt grizzlies in the lower 48 since 1973 I think) I defer to Phil Shoemaker who has on many occasions said the 30-06 is a reasonable minimum. Having seen and killed one up close with a 375 H&H, I think with good shot placement and a premium bullet a 180g to 220g bullet in a 30-06 should do the job. The closer you are, the smaller it will seem though.
