That IS impressive. But then comes the inevitable question: will that load shoot the same at 20 degrees F as it does at 90 degrees F?
The inevitable question is does it matter if you don't hunt when it's 90 degrees? One of the worst for temp stability is H414 and I've killed more game with H414 than a lot of people have killed. It's a big deal in a precision rifle used to shoot metal at 1100 yards, not such a big thing in a hunting rifle.
