Bakes,
Not applicable with todays bullets, a failsafe, BarnesX, GS Customs, Northfork, or any good super premium will penitrate more the faster you drive it, at least up to a point....Not so with the old standard soft points..

That is yesteryears thinking...

I have shot a lot of .270s and most shot very well indeed, as much so as any other caliber and they kill as well as a 30-06, in fact there is precious little difference in the .270, 06, 280, 7 mag and a host of others except in the minds of some folks.
