................And that makes sense! The same effect, as the lead sled, without the detremental aspects of the lead sled, can be had by useing a ruck sack with a long strap. Place the weight inside the bag, and place the bag on the bench, with the strap between you and the butt of the rifle. When the rifle is fired the recoil pulls the bag back with the rifle, and your shoulder. With the elbows rested on the bench, and the fore-hand resting on a sand bag holding the rifle as if shooting off hand, no strain is trasmitted to the rifle at all,and it is as free to recoil any way it wants, but still lessens the felt recoil for the shooter, and does nothing to interfere with the shooting to the rifle's regulation! It is the same prencible,as the lead sled, but leaves the butt of the rifle only touching the shoulder, not resting on the hard bottom of the butt slot in the lead sled. I've used this for years while performing the regulation of barrel sets on large chamberings like the 577NE, to reduce the recoil, without a problem. My regulation will consistantly place two shots out of each barrel for a four shot composite group that will stay on a standard playing card @ 50 yds, without crossing!
