This is the best shooting platform in the universe - Caldwell Lead Sled DFT 336647

Assembly directions were easy to follow but there was no mention of oiling the bearing and other threaded parts. A little oil on these not only makes for smoother operation but also protects against rust. This is a great platform for sighting in a rifle and for shooting with all of the adjustments which can be made for elevation and windage.

Full 25 pound shot bags when inserted into the Caldwell bags will not fit under the rails. Pour half of the shot into a quart freezer bag, use duct tape to reinforce the zipper end and then insert this bag into another freezer bag and reinforce that bag's zipper end with duct tape. Then insert the freezer bag into the Caldwell bag. These 12.50 pound bags fit the tray perfectly and will slide under the rails. Or 2 Caldwell bags . . . each filled with 25 pounds of shot can be placed on the each side by positioning them on top of the trays by the rails. It seems that #9 lead shot works best in either application.
