The barrel is floated. After some thinking, I realized that it's the first shot that really counts when out deer hunting. Then, and at the range, for the first shot the barrel is cold and accurate every time. It just seems to be very difficult to repeat tight groups unless I let the barrel cool down significantly after each shot.
Incidentally, the notion to remove some from the barrel comes from the book Understanding Firearm Ballistics 6th Edition Rinker page 64.
By the way, thanks for the responses.
