....I'm not yet convinced it's best, although it seems stable. I can easily pull off the long bipod legs but I keep the prone level bipod on the rifle at all times.
I wish I had a pic of Eddie Horne's setup. Probably one of the best unsung shooters around. Might see him once a year, might not. He's a black powder, archery guy that has keen range estimating skills and a good eye for what works with equipment.
His "bipod/shooting sticks" were made of two legs of a camera tripod. He made a u-shaped cradle lined with a stiff foam to set the rifle in. If I remember correctly, maybe the third leg was cut off about 6" from the top and made for a good place to hold. Very good setup.
