8 gauge choke dimensions

[Mike of the Mountain]

Might have to rely on a pattern test at 30 yards to determine the choke. In theory, the only choke that should throw a 100% pattern at 30 yards inside a 30" circle is full. 20 yards is too close and 40 yards is farther than needed.

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.

But Parker Bros. Standard pattern board test for most gauges and at which distance the choke was determined, was 40 yards.

Theoretically speaking, at 40 yards you won't have any choke pattern at 100% with modern load data. Plus, why step off another 10 yards when it's not needed.
