One hole groups from a gun every time it goes to the range for what ever reason, and for how many shots fired, is not a possible reality. I have been told of these guns, but yet to see one, Everybody shoots a screamer or two now and then, some refer to them as "wallet groups" to show off. Competition shooters often refer to how well they are shooting by what their aggregate is, which means "ALL" groups, not just the best are added together and averaged out. All them "oops" shots are figured in. For no other reason other than my own, this is how I refer to my firearms when asked. Every time I shoot a group, regardless of group quantity, with any of my guns I keep a record of group size, date and conditions. plus load data. I start from day one shooting the gun, in whatever the conditions of the day are. There are target firearms and there are hunting firearms, it is possible to combine the two but more easily said than done.
