JWALL, When I got into reloading 270's, back in the early 70's, 4064 was commonly used by many folks. It was, and is, a pretty effective package.
Over several decades of loading several 270's, I have found the caliber pretty easy to get along with.
Perhaps out of context: Mule Deer once quoted a friend of his to the effect that a case full on nitrated manure under a good bullet would likely shoot well.


Imagine your grave on a windy winter night. You've been dead for 70 years.
It's been 50 since a visitor last paused at your tombstone.....
Now explain why you're in a pissy mood today.
