I did not confirm the ES but the accuracy was in the .3 realm. Based on my experience 40.8 will shine since it's in the middle of the ladder and probably the most stable regarding harmonics.
full disclosure: I did not like the #3 contour barrel for the rate of fire I normally run and the stock it was going in. I had asked a smith to throat this barrel a bit longer for a future project and became a bit concerned with his "free hand technique" and stopped him from continuing. To ensure he did no harm I took it to a trusted builder at Mile high Shooting in Erie, Colorado. He did a barrel setback and we screwed it on my 700 action and ran the above ladder test…issue avoided.
