For me, practical accuracy is: how closely a rifle will shoot within a radius to point of aim. This meaning that the group POI will not shift at any practical range within normal field shooting conditions to yield groups larger then 2 inches at 300 yards. All of the four guns which I still use since retirement, will reliably shoot a one inch radius group to POA group at 300 yards. They all will also continuing this accuracy trend beyond 300 yards with my loads, assuming that I do my part with shooting form. This does not include my 9.3x74R which will meet this criteria at 200 yards. This practically limits my hunting shots to about 400 yards under field conditions on deer sized animals and elk at 300 yards with the 9.3mm.

Actually, finding, testing and proving these rifles to be keepers is tougher than it sounds. I have owned many rifles in my 73 years and only a couple of handfuls of these rifles have met this accuracy criteria over years of use.
