I use a basic Caldwell front rest with a bag rest for sporters. It seems closest to the "average" type of rest position I would use where an accurate shot was required. Stay very conscious of any forearm support with the off hand, rearward pull pressure of the stock into the shoulder, and the degree of cheek weld pressure(which should be minimal). If a bi-pod was anticipated to be used to a great extent, I would substitute the Caldwell(or other) front rest for the bi-pod…..Or devote some time shooting on the bi-pod, post load development, if occasional use of a bi-pod were anticipated.
