Home Forums Hunting & Shooting Hunting Rifles 280AI vs 270 Winchester

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.

For Berger bullets the highest BC you can get in .270 is .662, for the .280 it's .755.

And so on and so forth.
