i would leave the bipod home and go get a set of shooting sticks. they work great on any angle ofground. back tothe bipods. the 6 to 9 inchbipod is what we use on the bench if we use them at all. a 9 to 12 inch is the best for laying down. and the 14 to 27 inch works best for the sitting shots. i still thinkif you give the sticks a try you will nevergo back to bipods.
