With 10" Contenders I have found that I can shoot reasonablly accurately using a Kneeling Position. Basically I get into a kneeling position like a person would shooting a rifle. My left elbow (I am right handed) goes on top of my left knee and my right shooting hand goes into my left hand. The left forearm is nearly verticle to supply as much support as possible. This is reasonablly steady out to about 100 yards (or slightly more on a good day) when I have practiced on my 10" Metal Gong. Now granted I have used this postition only when there was no other rest available, and only with 10" Barrels.
However I mainly use two different rests (depending on the type of hunting I am doing). For the times I might have to take a shot while I am standing I normally have a walking stick with me. This is nothing more than a Ski Pole with the basket removed. On the top of the handle I have attached a "Y" made out of plastic for a Gun Rest. This is not the greatest in stability, but does indeed help.
Otherwise when I know I am going to be sitting I use a set of home made crossed shooting sticks. Mine are made out of two telescoping sections of alluminum tubing (with a friction nut to adust the length). I have found that from a sitting position, as long as I can get my left elbow on my left knee for added support, quite accurate shooting can be acomplished with these sticks.

PS I have recently made a couple sets of crossed shooting sticks for some friends out of 5/8" diameter 36" long wooden dowel. I just joined them 4" from the top with a cross bolt, and put 5/8" Black Heater Hose on the tops of the sticks for the Gun to rest in quietly. I also drilled a hole in the bottom portion of each stick and put 36" of small nylon cord through the holes. This keeps the sticks from extending too far apart, and also serves as sort of a sling to carry the sticks upside down when walking. My two buddies tried them out this past week and phoned to tell me how well they liked them.
