There a number of companies that make choke tubes. There is a reason that they exist, that being that the tubes that come with most guns don't work the way they should.
Here is an interesting link from the Briley web site ...

There is no math to do here. There is no consistent relationship between shot sizes. If size 8 patterns a certain way with a certain choke it may or may not pattern as well with 7 1/2 shot. eg. a 7 1/2 shot pattern may be very even and uniform and have large target sized holes with #8 shot. What patterns well with 2 3/4 dram eq. may not pattern well with 3 dram eq. So you see, there is no math to be done here?- same exercise for 7-1/2 and for 8. So, do the math, lol
Ok, here it goes:
Shotgun: 12 Ga Fabarm SAT 8 Proforces, semi-auto, 20" bbl.
#8 AA Win heavy load, CYL (0;.000), 20m
#8 AA Win heavy load, I/C (1/4;.012), 20m
#8 AA Win heavy load, MOD (1/2;.023), 20m
#8 AA Win heavy load, FULL (1/1;.043), 20m
#7.5 AA Win heavy load, MOD (1/2;.023), 35m
#7.5 AA Win heavy load, I/M (3/4;.027), 35m
#7.5 AA Win heavy load, FULL (1/1;.043), 35m
Nice patterns Henry should be jealous.
I actually thought the IM at 35m pattern was a bit high, but saw no spots where a target may have got through. Maybe some of those spots on the pic are not pellet holes? I did not comment on this pattern because, with a 20 inch barrel at longer range, it is kinda like trying to be a #### star without the proper equipment.
Lol!
Here is something to start the argument,[B] lol[/B]
Mr Barnes in his book "the Cartridges of the World" 12th edition says that with modern [shotgun] shells, the combustion occurs before you reach minimum legal barrell length (18.5") and chokes take care of the pattern, so barrell length has the most to do with the feel and balance of the gun and not what the gun is able to pattern. Shorter bbls are quicker pointing, but somewhat less stable. When people talk barrell lengths, don't forget that an auto or pump has about 4" of receiver that a double has incorporated into the barrells, so make sure to add about 4" to an auto bbl to get the equivilent double (SxS or O/U) length. According to Mr Barnes I have 26" barrel: 20" barrel + 4" receiver + 2" choke.
That day in the club when I shot the patterns I posted, I heard one older gentleman who was shooting clay that day, saying behind my back to his buddy - "she thinks she is going to hit anything from here with this shorty? Ha!" (I was shooting from 35m). After I brought the target back and showed him that I did actually hit "something", he told me he was impressed with the result and asked me for my shotgun specs.
No argument here! Got both! Doubles and autos. Long and Short. I am not sure why anyone would think anyone could not hit a stationary target at 35m?
Shorter bbls are quicker pointing, but somewhat less stable. My point exactly! At longer range quartering targets (not stationary) where IM or full is required, smoother more controled and more stable is required. My point in my previous post is that I thought your IM was fine for breaking clay, but I did not suggest using it. I suggested cylinder and modified because of your gun specs. Sure your 20 inch auto will break clay at longer yardage, but it does not have the best steering. Longer guns are better suited for longer range moving targets.
