A good project for your new 8 Mike!
Just looking for a published standard, as exists for every other common gauge.

I may just do that. Usually don't pattern any guns unless I'm using said gun for turkey, then I'll shoot a know distance at a turkey head/neck target since that is the same thing as shooting at a live turkey. Might do a point of impact test, but not a pattern.
