I echoCayugad input - think it was right one the mark with what I have found...
The only thing I would add/subtract which ever way you want to look at it is, the longer the berrel the longer it will take you to get on the target.2nd I really prefer the shorter barrel for most of the hunting that I do because I hunt in a lot of covered timber stands andbrush. It is much easier to wheel and work a short barrel in those circumstances. If you were a tree stand hunter i believe the advantage there would also go to the shorter barrel...
Amoung the ML's that I have, I do have 2 Remington's one is the shorter, and older,24" model and the other is the 26" model - they shoot identically. I do NOT shoot the 150 grain loads... 110 grains of T7-2f.
Keep asking questions - you will get a variety of answers that you will make a decision - hopefully it will be an informed decision though...
