A 150 grain .270 bullet will do anything a 180 grain .30 caliber bullet will do. So will a 160 grain 7mm bullet, or a 140 grain 6.5mm bullet.
I agree, AS LONG AS you use "premium" bullets for the heavier animials. Higher velicity = shredded bullets!! SO, use a bullet that can stand the higher V so you get the proper penetration!!

Oh yeah, in the 75 years since the introduction of the .270 bullet makers couldn't design an adequate bullet until the introduction of the super magnum. [:-]
