I think from now on, (except maybe target rifle and ground hog rifle )I'm just going to be shooting 2 shot groups to sight in my Handi's and my other deer rifles, even my Black Powder rifles. I never fire more than 2 rounds in deer hunting. I know a lot of my rifles, first 2 shots are usually touching and the 3rd is usually my group spoiler.........what da ya think? :?
