FWIW I put a few hundred rounds (couple thousand?)through my 30-284 attempting to ring out the most velocity I could from 130, 150, 165, 168. and 180 grain bullets of various manufacturers.
It would parallel the hot 30-06 loads but I was never able to gain much over the -06.
What I found was that it appeared to be a ballistic twin to the -06. It appeared to like H4350 powder.

BE STRONG IN THE LORD, AND IN HIS MIGHTY POWER. ~ Ephesians 6:10

Socialism is a philosophy of failure,
the creed of ignorance,
and the gospel of envy,
its inherent virtue is the equal sharing of misery.
--Winston Churchill
