BTW, for accuracy tests, you may want to give Elmer Keith's two-handed seated position a try.
It's shown in his book, "Sixguns", of which you should have a copy. Skeeter Skelton and Jeff Cooper also used much the same position. It's very steady.
T-Star: I've tried that position, it's very steady. Once we were out in the desert checking accuracy of some snubbies: even from that position, they were giving pretty large groups; it's hard to get the exacting sight picture you need for accuracy with those guns having such a short sight radius. I was beginning to doubt my shooting ability but we finished up with a K 38; nice small group, I told my friend "My hand has not yet lost its skill".
