Thanks, Allen. They are about 3,900. My trigger hand is well supported, my son's, too, usually, though he was unsupported in the photo. At first the short tabletop drove me nuts, but now I shoot across it, diagnally, and use the Caldwell bag instead of a bipod. That way I have room for great support for' and aft'. (See what the marine compasses are doing?

) My only complaint is that with any portable, the table (and you) get blown around a bit in a good breeze, and the table moves in recoil more than a good, solid bench at the range. However, two of them do not take up much room, don't weigh much (for those times we are forced to pack them a couple hundred yards) and they swivel 360 degrees. I have grown to really like them.
