thats varmint al's page and his famous "by-fur-pod".its a very good site that every serious predator hunter should visit often.

Harris bipods are worth the money. Just about anything will work for homeade shooting sticks, but I may have to try what beachhunter did. Sounds pretty good.

Stoney point sticks are nice and so are harris bipods. If you will do a lot of shooting standing up go for the shooting sticks.
