I'm too tired to read all the posts. My 2 cents, Harris bipod. I use the bigger guy that allows me to shoot it sitting Indian style. Don't know the model #. Used it in Africa and all over Arizona and Colorado for elk and muledeer. On a Weatherby Mark 5 300 Weatherby mag with a BC stock. Bit big and troublesome on the shoulder but it takes a 300 yard shoot off a backpack and turns it into a 500 yard last light monster buck shot.but
