I was interested in building a similar rifle. I saw the 700 Long Range on the shelf and had to have it!
I have made several modifications to this rifle including a full trigger job including swapping the springs, modifying the bolt handle (There is more function here than it seems, the old bolt handle used to hit my finger on every recoil.) and I had a JP Eliminator muzzle brake
I did my first round of load development and got a beauty of a group at .323"!
