I decided to scrap my 270wsm project and start on a good long range rifle. I was considering a 280, any ideas? The 284 Winchester also interest me. I would like to stay in the .284 bullet size. What is it that makes a good long range calibur? I know the 7mag is popular but I was under the impression it is not that fast. I always thought fast was flat and flat was accurate. But the more I learn the more I learn I don't know. Any thoughts would be appreciated.
