A few years ago I had a .300 Win Mag built with a Sako action and Shilen barrel. The stock is a HS Precision synthetic. I asked the gunsmith if, in his opinion, the barrel should be full-length bedded or floated. He recommended that it be full-length bedded. The rifle shoots fine but I'm wondering if it would shoot better if I floated the barrel?

That's bass ackwards. On something like that it's generally customary to try floating the barrel first and then add epoxy if it doesn't behave. If you now remove the epoxy and it doesn't perform any better, you might be able to pull it back together with a little pressure bedding rather that the full length stuff. I would have recommended trying it floated first.

Forbes seems to have good luck bedding his ULA's full length, I'd call it a matter of preferance. If it's shooting fine why mess with it? You can probably do more improvements with shooting technique,practice and loading than by messing with the rifle.

Wait your both right some prefer it some don't !.

But full floating is the first obvious choice !.
