Default 8 gauge choke dimensions

I recently went looking for a listing of choke dimensions for the 8 gauge, and came up with.......nothing.
Greener, Howe, Dunlap and TPS, zip, nada!

Having the opportunity to measure a number of 8 gauges recently, I found a large variability.

So, does anyone have a reference which published "standard" choke dimensions for the 8 gauge

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.

I do not have any published data but do have three Parkers with letters that specify choke, 60660 8ga O grade letter says RH 115 #4 pellets in a 30" circle at 40 yards LH same. The chokes measure .025/.026. 157318 PH 8ga specifies in the letter RH modified, LH full and the chokes measure .038/.042. 161252 GH 8ga specifies in the letter to pattern with BB shot RH full, LH full. The chokes measure .046/.045.
It seems to me from a very limited sample that the restrictions are the same you would encounter in 12 and 10ga guns.

Makes sense to me Craig. .025/.026 should be IM/IM, .038/.042 should be F/XF and .046/.045 should be XF/XF.
