    Is there a standard for testing patterning? I.e. a certain diameter in which you measure the percentage of your shot in?

    Yes, for everything except the 410, the "standard" is to shoot from 40 yards and draw a circle around the greatest number of holes that can be contained in a 30 inch circle. The pattern percentages obtained is what determines the choke designation ---- for example 50 to 59 percent is Improved/Cylinder -----60 to 69 is Modified and anything over 70% is Full, etc. Chokes like Light/Full or Improved/Modified, etc fit in the upper and lower ranges listed.

    While 40 yards is the "standard", it isn't always the best yardage for everthing; skeet shooters tend to shoot their patterns at 21 yards as that is the distance to the center stake and is typically the furthest distance that many will break their targets.
