I have a Caldwell Lead Sled...it is a very good shooting rest,with good front and rear pads for recoil and You simply weight it down and then adjust the level to get on target.It is built well and isn't made of the light weight cheap plastic some Gun Rest are.I gave around $125.00 for mine and I have seen them on sale cheaper than that,plus they came out with a newer version that has 2 bottom trays to put more weight in.
