A lot of people use the Harris 6-9" swivel bipod. Some use the Sinclair F-Class. It is what works best for you. I started using the Harris but didn't like the way it hopped every time I broke a shot.
Using the Harris you have to preload it or lean into it and grip the rifle pretty tight at the back to help control recoil. The bipod always tried to skoot away from me, some would replace the feet with pod claws to get a better grip but some ranges have concrete firing lines. I built mine similar to the Sinclair, with that type you let the rifle recoil as long as you have it set-up to recoil straight back. Get a rear bag that your butt stock will fit in the ears all the way to the bottom nice and snug. One with stiff walls that won't roll around on you because you don't want to have to fight it to keep it in position during your string. Fill it with heavy sand that you can get from Sinclair.
