Here is a group I shot that I thought was pretty good (probably my best at this distance). I normally shoot 5 shot groups but this was during load development and I was getting scope elevation information at the same time. The group measured .893" center to center and was shot from 400 yards. I have no reason to think that it won't do better, but I might not be able to do better...we'll see.
