May want to look into a good shooting jacket for siting in and padded comfy jacket during hunting.The heart beat can add some movement sometimes,and the thought of recoil will elevate the heart rate.I shoot over sand bags at range with a oylimpic style jacket,during hunting a coat or jacket takes it's place.The lead sled maybe fine but it seems the rifle should have the recoil absorbed more gradual than dead stop.Smaller calibers would be ok but larger belted rounds may need to roll so the tang and lug aren't stressed,I've heard somewhere of big guns cracking when not allowed to push through,it's stopping a natural reaction to recoil too fast!
