Use a sand bag to cradle the trigger gaurd and as much of the barrel as you can. Setting the butt of the gun on the bench to steady it will give you a weird bounce and you will have a hard time maintaining any consistant point of impact. I learned that when shooting ICORE competition, especially at the prone position 50 yard target.
Better yet, just send that whole collection of crappy wheelguns to me and I'll see if they can really shoot!
