I have a 270 WSM with a Lilja #5 CM barrel. A local gunsmith put flutes into it before mating it to the action. He said that it would be fine as long as your careful to not generate too much heat while fluting. Well, the rifle shoots under 1/2" groups all day and I get good velocity out of it as well. My need for this rifle as a long range tool has changed since I've had my Edge built. Now I want to turn it into a lightweight pack rifle. My question is, can I have the barrel turned down to a #3 or even a #2?
