What type of shooting do you prefer? As you have bought a Sinclair f class bipod I will assume that you like the ski pod design (remple/censhot/bigfoot) which allows the rifle to slide back and forth easily.
Are you closer to free recoiler then a firm anchored grip?
If you want the tracking to be straight back under a slight free recoiling system you will need to look at stock designs that have gradual inclines of the rear butt section not unlike a bench rest stock that allows the rifle to track with little change in elevation which becomes more critical for long range shooters. The traditional target stock have a high degree of cant like the Robertson composite H&H while others have a butt hook or flat bottom like Robertson tactical or the McMillian A3/A5. Charles Ballard the open class winner 2 years ago has come out with a lowrider stock that has the flatter bottom which may appeal to you. Other features are adjustability cheek piece an adjustable butt plates. These 2 features can be put on almost any rifle stock.
Fit and feel is important if you�re constantly fidgeting with your position to fit the stock you will be guaranteed to drop points.
