Im getting ready to start my first custom build. The rifle im using is a Kimber 8400 30-06. My first plan was to make it a 6.5x284 norma. After doing some research on other calibers, I found the 6.5x47 lapua. Will the 30-06 long action be a good candidate 6.5x47? They seem to be real close to the same ballistics. I have also read that the 6.5x47 has alot longer barrel life. Any advice on these two calibers would be great!
