A few years ago I bought a Biesen .280 built on a G33/40 action. It was built as a spec rifle and thus has all the bells and whistles. IMO it was built right for that action in that it weighs about 7 3/4 lbs scoped. Octagon barrel of unknown brand. When I first saw it I started thinking about that light barrel, light rifle blah blah. I was hoping it would shoot around an inch and I would not have been too disappointed if did an 1 1/4. First time to the range I shot three three shot groups that were from .6" down to a little under .4". I was almost dumfounded. Do not know if most Biesens shoot that well, but what a pleasant surprise.
