I looked at the lead sled and noticed that several of the people that hand them were using bungy cords to secure them to the shooting table. Hmm......For me, I thought it was too big and heavy. There is a limit to how you can place the forearm of a rifle, although I usually sit it in there with the sling swivel butt up against the front rest. That way I place my rifle in the same position every time after there is any recoil. My rifles don't move very much so it works for me. Anyway, I didn't want to spend upward of $100 on a shooter rest. The matrix beats using sandbags.The simple versions of the lead sled such as the solo doesn't really give you much adjustment on where the forearm lays on the the front bag. I like the tripod bag in front and a rabbit ear or a bean bag or even nothing in the back. Some of my levers are picky about where you rest the front and this is where I like to be able to move the front rest around as needed. I find that many times resting right in front of the lever gets me pretty good accuracy for bench shooting. Ymmv.
