ok, I floated the barrel. I only had and could find one o ring laying around and it was small, so I took an old credit card and cut it up and drilled holes in the center of it to fit over the barrel stud. IN all I used the small o ring, and two peices of card put together to get the barrel floated. I can now take two sheets of paper and run them between the barrel and the forend up to the barrel stud. Does this sound like a good fix? Will the peices of old credit card(plastic) be ok for this float job??? I must say it did a good job free floating the barrel as long as the plastic does not give and compress over time, this barrel should stay floated. What do you all think? Is there a such thing as to floated?? I would guess that the two pieces of card and o ring together are about 1/16" maybe 3/32" . Thanks again.

For a rest I was using sand bags. The cross hairs seemed steady as a rock on my aim.
