I called Melvin today and asked the question, keep in mind it's a 6.5 Creedmoor with a 22" barrel,

"What would I gain by going to a #2 contour?",

his answer was simply

"Weight".

So then I asked the question

"How will it balance compared to my model 24 280ai with a 24" #2 contour barrel?",

his answer

"Exactly the same, what I do north of the guard screw I do south of the guard screw, there is weight added to the back end of your 280ai."

I think I'm going to just go with the #1 contour, my theory is it's all about the balance, if it's a well balanced ultralight rifle it will hold on target better than a heavy rifle that isn't balanced. Nula's are different from pretty much every other rifle in that there is just as much, if not more attention put into the stock as there is to the action and barrel.
