As used in the latest 1000 yard benchrest group of a little over 1" for five shots - shot from a rifle that looks like a rifle and not a piece of laboratory equipment. Used to be made right there at the competition site by Swampy Knox in his truck - J4 jackets and all, sold still hot. He WAS JLK - but sold out to another husband and wife team of national-level BR-ers.
Here in UK it's Fox Firearms who has them -
