When I pull out my elk rifle every year I don't think about short range and slow and heavy. I think about what if that bull is standing 500 yds from me above timberline and there's not a bush big enough to hide a rabbit behind between him and me. That's what crosses my mind. So I prefer speed and trajectory and accuracy over heavy bullets. I guess that's what makes me different. I won't explain in detail just pull some numbers off remington's charts for example's. Then I'll list my hand load at the bottom.

The 270's 130gr factory loads compete really well against the 30-06's factory loads in two heavier grain bullets. Of course this is 300yds and beyond. The 270win is a lot flatter and would be a lot easier to judge hold over or adjust clicks on a target scope. I put my data in the mix to show you at those ranges my hand loads are flying faster, hitting harder, and have a lot less room for error than of a standard factory load in a 30-06. I love the 30-06 round it's a great one. But it don't have what i'm looking for in my long range shooting and ballistic coefficient in down range shooting. If I were to only shoot 200yds and under sure why not load the ole 30-06 with 200gr bullets and get after it.
So to say I'll choose the 30-06 over the 270 win in my gun cabinet I'd have to say that ole model 70 30-06 has been collecting dust for a lot of years now.
Sorry for the charts the site wouldn't let me copy and paste the originals. I posted this to put a lot of myths to bed. They are both from the same case but different in bore size. Both can hold the same amount of powder but one can push a bullet a tad faster is all and the other can be loaded with a heavier bullet. That's about the size of it.
