It's clear that many posters here don't have a grasp of what causes hits vs. misses at various distances. Shooting at say 600y at an elk sized target (let's say 12" round vitals), a cartridge's drop is not even worth talking about. You bought a range finder and know how to push the button and turn a scope knob. Shooter and rifle accuracy is only moderately relevant - 1 to 1.5 MOA will get it done. But wind call error will turn a hit into a miss (or a gut shot) in a hurry. And windage is where the big case, high BC rifles excel. It's easy for a great configuration to have 1/2 the wind drift of a mediocre one. Even the piddly little 6.5CM stomps the .270 there. Compared to an equivalent action and bore diameter cartridge like the 28 Nosler, the .270 just hangs its head in shame. And no amount of skill will totally eliminate wind call error - western terrain tends to be very concave, and your shots can pass 100s of feet above the ground. There are no wind flags up there. It's just a guess based on what you can see on the ground, feel, and some basic rules about weather. How far you can ethically shoot end up being primarily a function of the cartridge and bullet you choose.

The .270 was a failure of engineering (some the US gov, some Winchester) from day one. It's only fitting that it's the chosen tool of incompetent shooters.
