Every No4Mk1 or similar Enfield I have ever had shot best when the barrel was free floated the way they were from the factory.
Some say that these rifles needed upward muzzle pressure, I have never had one that benefited from such modifications.
The No1Mk111 is a different animal, most that I have had shot best with pressure at the middle band and at the nosecap.
Being that your rifle is new from the wrap, I suspect the wood has warped slightly and needs to be free floated again.
