That's an interesting article. I would have liked to have known about it a couple of years ago when I was working with an ultra light in 280AI (just under 5 pounds without scope). My experience was that light rifles were really challenging to shoot accurately, one time I could shoot out and the next I couldn't hit anything. If I still had my 280AI (it's out on consignment at a shop) I would try some of these techniques, I've since moved on t from the minimalist weight school of thought.
