RE: anyone know how to stablize guns?
I don't but know many who use a sling to stabilize when shooting. Basically rap the sling around your elbow, it forms a triangle.
Also know some guys that tuck their stock arm into their body and swear it helps.
These are thought, since I don't really notice a problem, if close range. Long range I usually sit with my knees up and rest my elbow on the knee or find a solid rest like a fence post or tree.
