"One of the hot-stove-league arguments now going on is whether the .30/06 or the .270 is the better big game cartridge. I have hunted for years with both calibers. Right now I have three .30-06's and three .270's. And that, I believe, shows how I feel.
As I see it, the 200-foot-seconds greater velocity of the 130-gr. .270 factory load gives it a slight edge over the 150-gr. .30/06 on lighter animals like deer, antelope and sheep. This .270 load also has a somewhat longer point-blank range, 275 yd. or thereabouts when the rifle is sighted in to put the bullet 4 in high at 200 . The point-blank range would be 250 yd. in the .30/06. A somewhat higher impact velocity at the longer ranges gives the .270, I believe, a higher percentage of instant kills than the .30/06. Flatter trajectory plus slightly less punishing recoil means that many hunters can do more accurate shooting with the .270.
On the other hand, the .30/06's heavier bullets make it a little superior on the larger animals. So while it's my belief that the .270 has the edge on lighter game, I'd give the .30/06 the nod on heavier animals. I doubt that anything that can be put through a .270 would be quite as effective on the heavier stuff as a good 180 grain bullet in the .30/06. And when a man is hunting really heavy and potentially dangerous game I don't think any .270 load is as effective as a good 220 gr. bullet in the .30/06, as these babies play for keeps and the bullet must drive into the vitals at all costs! Friends of mine who have hunted in Africa with the .270 and .30-06 say the latter's 220 gr. bullet is far more effective on big game than the .270 with any load."
