Real accuracy buffs use 5 and 10 shot groups, not 2, or 3 nor 4. But if it makes you happy shooting 2,3 or 4 shot groups go for it!

heck, the best groups I shoot are only 1 doubleA

.......really, knowing where that first shot is going is the most important thing, tiny groups of under .100" dont take big game any better that a rifle that does 1" out to....... say 500 yards, in which most shots are well under that.
