Tried a search.

Looking to build a rifle for long range target shooting/hunting. Everything is a compromise but this is what we're going for:

Sub moa accuracy out to 800-1k yards.

Lethality on med size game out to 500 yards.

.270 Win- Flat shooting, acceptable lethality, mediocre bullet selection, some 150's in the high.5 bc's, great velocity.

.30-06- Timeless performance and accuracy potential. Great bullet selection. Can shootthe heavier bullets with the higher bc's but lacks the velocity of the .270.

.300 Win Mag. Good velocity, same great bullet selction as the .30-06, awesome lethality, astronomical powder charges.

Not against going with the .300, seems like the .30-06 is in a simmilar ring, if so than why not the .270?
