For that type of shooting i would say 22".
I say 22" for both weight and MV in Grendel.
Personally, I always struggle with the 18" for long range. I have shot several and find them generally to be too light weight overall and too short making it difficult to keep steady on the rest or bags. They are very sensitive to trigger pull weight which is critical. My shortest AR long gun is 20" with weight added to the stock. The others are all 22"-26".
You have to be a really good to manage a short light barrel in the long game.
So the next question is barrel diameter...
