Depends on the gun... at what point, from absolutely clean, does the gun start to group well, and at what point without cleaning, does the gun's groups start to open up, if at all, that you can tell?

In other words... using the same ammo, if 3-4 shots from a clean barrel and the gun settles down to group constantly... then after say, 60 shots it starts to show signs of the groups opening up... then your working range is maybe 5 shots to settle in and maybe 50-55 shots before cleaning again.

If you don't know this... then maybe you'll get to find out with the testing.
