I am looking for a better rest than the Caldwell green sand bag I have been using for years, I looked at the Caldwell "the rock" but did not like the fact that the base was cast aluminum. The lead sled for a few dollars more looked more sturdy. I do not need a lead sled for recoil purposes but I am considering buying one just as a more solid rifle rest and use it without the added weight bags. Should I ever need to use it for a heavier rifle, then I have it. Will a rifle's point of impact be different from a lead sled than off of a sand bag? I have heard some that say it will and others that say it will not???
