Someone please explain what "better" bullet selection means?
You need it explained?
It has to do with both size and BC. For example if you think you need a stout, heavier bullet for big animals the biggest Partition you can shoot in your .270 is 160 grains; the biggest for the .280 is 175 grains. The heaviest TTSX Barnes lists for the .270 is 130 grains; for the .280 it's 150.
Woodleigh do a 180 grain .270cal
.270cal TSX is available in 130,140,150
Yes, I know. And there are others that make big bullets for .270s, like Matrix. But if you go back and look at the post I was responding to, you'll see that the poster specifically mentioned a few different brands and makes of bullets, including Bergers, TTSXs, and Partitions, so his examples are what I used to show that bigger bullets are available in the .280..
